APDS9930 Ambient Light and Proximity sensor
|
|
||||||
===========================================
|
|
||||||
|
|
||||||
This is a fork of the [library from Sparkfun for the APDS-9960 sensor](https://github.com/sparkfun/APDS-9960_RGB_and_Gesture_Sensor). It has been adapted to read values from this other model.
|
|
||||||
|
|
||||||
[**Quick-start guide available here**](https://web.archive.org/web/20151224052223/http://davideddu.org/blog/posts/apds-9930-arduino-quickstart/)

# DO NOT EMAIL ME IF YOU HAVE AN ISSUE
|
|
||||||
It will be deleted without reading. If you have an issue, [create an issue](https://github.com/Depau/APDS9930/issues) here on GitHub.
|
|
||||||
|
|
||||||
# Unmaintained
|
|
||||||
I'm not going to maintain this library any more. I will merge pull requests, though. Contributions are welcome. Just don't expect anything from me.
|
|
||||||

|
|
||||||
|
|
||||||
**Note:** even though it says APDS-9960, it's an APDS-9930. That's how I ended up getting one of those. I wanted the RGB sensor. I found this crap in my mailbox. But I decided to write a library for it anyways ;)
|
|
||||||
|
|
||||||
Getting Started
|
|
||||||
---------------
|
|
||||||
|
|
||||||
* Download the Git repository as a ZIP ("Download ZIP" button)
|
|
||||||
* Unzip
|
|
||||||
* Copy the entire library directory (APDS-9930) to
|
|
||||||
\<Arduino installation directory\>/libraries
|
|
||||||
* Open the Arduino program
|
|
||||||
* Select File -> Examples -> APDS9930 -> GestureTest
|
|
||||||
* Plug in your Arduino and APDS-9930 with the following connections
|
|
||||||
|
|
||||||
*-OR-*
|
|
||||||
|
|
||||||
* Use the library manager
|
|
||||||
|
|
||||||
| Arduino Pin | APDS-9930 Board | Function |
|
|
||||||
|---|---|---|
|
|
||||||
| 3.3V | VCC | Power |
|
|
||||||
| GND | GND | Ground |
|
|
||||||
| A4 | SDA | I²C Data |
|
|
||||||
| A5 | SCL | I²C Clock |
|
|
||||||
| 2 | INT | Interrupt |
|
|
||||||
|
|
||||||
*P.S.: you already know you can't use this purple little thing with your 5V Arduino without a level shifter, right? :) In case you don't have a level shifter, you can detach the microcontroller from an Arduino Uno, reconnect the oscillator pins, the RX and TX pins, the reset and the LED/SCK pins back to the board with some jumper wires. You can then power the microcontroller from a 3.3V source (the 3V3 output on the board should work) and connect the sensor directly to the MCU. Look up "Arduino on Breadboard".*
|
|
||||||
|
|
||||||
* Go to Tools -> Board and select your Arduino board
|
|
||||||
* Go to Tools -> Serial Port and select the COM port of your Arduino board
|
|
||||||
* Click "Upload"
|
|
||||||
* Go to Tools -> Serial Monitor
|
|
||||||
* Ensure the baud rate is set at 9600 baud
|
|
||||||
* Swipe your hand over the sensor in various directions!

|
|
||||||
|
|
||||||
Tests the ambient light interrupt abilities of the APDS-9930.
|
|
||||||
Configures the APDS-9930 over I2C and waits for an external
|
|
||||||
interrupt based on high or low light conditions. Try covering
|
|
||||||
the sensor with your hand or bringing the sensor close to a
|
|
||||||
bright light source. You might need to adjust the LIGHT_INT_HIGH
|
|
||||||
and LIGHT_INT_LOW values to get the interrupt to work correctly.
|
|
||||||
|
|
||||||
Hardware Connections:
|
|
||||||
|
|
||||||
IMPORTANT: The APDS-9930 can only accept 3.3V!

interrupt based on high or low proximity conditions. Move your
|
|
||||||
hand near the sensor and watch the LED on pin 13.

# Adafruit Community Code of Conduct
|
|
||||||
|
|
||||||
## Our Pledge
|
|
||||||
|
|
||||||
In the interest of fostering an open and welcoming environment, we as
|
|
||||||
contributors and leaders pledge to making participation in our project and
|
|
||||||
our community a harassment-free experience for everyone, regardless of age, body
|
|
||||||
size, disability, ethnicity, gender identity and expression, level or type of
|
|
||||||
experience, education, socio-economic status, nationality, personal appearance,
|
|
||||||
race, religion, or sexual identity and orientation.
|
|
||||||
|
|
||||||
## Our Standards
|
|
||||||
|
|
||||||
We are committed to providing a friendly, safe and welcoming environment for
|
|
||||||
all.
|
|
||||||
|
|
||||||
Examples of behavior that contributes to creating a positive environment
|
|
||||||
include:
|
|
||||||
|
|
||||||
* Be kind and courteous to others
|
|
||||||
* Using welcoming and inclusive language
|
|
||||||
* Being respectful of differing viewpoints and experiences
|
|
||||||
* Collaborating with other community members
|
|
||||||
* Gracefully accepting constructive criticism
|
|
||||||
* Focusing on what is best for the community
|
|
||||||
* Showing empathy towards other community members
|
|
||||||
|
|
||||||
Examples of unacceptable behavior by participants include:
|
|
||||||
|
|
||||||
* The use of sexualized language or imagery and sexual attention or advances
|
|
||||||
* The use of inappropriate images, including in a community member's avatar
|
|
||||||
* The use of inappropriate language, including in a community member's nickname
|
|
||||||
* Any spamming, flaming, baiting or other attention-stealing behavior
|
|
||||||
* Excessive or unwelcome helping; answering outside the scope of the question
|
|
||||||
asked
|
|
||||||
* Trolling, insulting/derogatory comments, and personal or political attacks
|
|
||||||
* Public or private harassment
|
|
||||||
* Publishing others' private information, such as a physical or electronic
|
|
||||||
address, without explicit permission
|
|
||||||
* Other conduct which could reasonably be considered inappropriate
|
|
||||||
|
|
||||||
The goal of the standards and moderation guidelines outlined here is to build
|
|
||||||
and maintain a respectful community. We ask that you don’t just aim to be
|
|
||||||
"technically unimpeachable", but rather try to be your best self.
|
|
||||||
|
|
||||||
We value many things beyond technical expertise, including collaboration and
|
|
||||||
supporting others within our community. Providing a positive experience for
|
|
||||||
other community members can have a much more significant impact than simply
|
|
||||||
providing the correct answer.
|
|
||||||
|
|
||||||
## Our Responsibilities
|
|
||||||
|
|
||||||
Project leaders are responsible for clarifying the standards of acceptable
|
|
||||||
behavior and are expected to take appropriate and fair corrective action in
|
|
||||||
response to any instances of unacceptable behavior.
|
|
||||||
|
|
||||||
Project leaders have the right and responsibility to remove, edit, or
|
|
||||||
reject messages, comments, commits, code, issues, and other contributions
|
|
||||||
that are not aligned to this Code of Conduct, or to ban temporarily or
|
|
||||||
permanently any community member for other behaviors that they deem
|
|

|
||||||
## Moderation
|
|
||||||
|
|
||||||
Instances of behaviors that violate the Adafruit Community Code of Conduct
|
|
||||||
may be reported by any member of the community. Community members are
|
|
||||||
encouraged to report these situations, including situations they witness
|
|
||||||
involving other community members.
|
|
||||||
|
|
||||||
You may report in the following ways:
|
|
||||||
|
|
||||||
In any situation, you may send an email to <support@adafruit.com>.
|
|
||||||
|
|
||||||
On the Adafruit Discord, you may send an open message from any channel
|
|
||||||
to all Community Helpers by tagging @community helpers. You may also send an
|
|
||||||
open message from any channel, or a direct message to @kattni#1507,
|
|
||||||
@tannewt#4653, @Dan Halbert#1614, @cater#2442, @sommersoft#0222, or
|
|
||||||
@Andon#8175.
|
|
||||||
|
|
||||||
Email and direct message reports will be kept confidential.
|
|
||||||
|
|
||||||
In situations on Discord where the issue is particularly egregious, possibly
|
|
||||||
illegal, requires immediate action, or violates the Discord terms of service,
|
|
||||||
you should also report the message directly to Discord.
|
|
||||||
|
|
||||||
These are the steps for upholding our community’s standards of conduct.
|
|
||||||
|
|
||||||
1. Any member of the community may report any situation that violates the
|
|
||||||
Adafruit Community Code of Conduct. All reports will be reviewed and
|
|
||||||
investigated.
|
|
||||||
2. If the behavior is an egregious violation, the community member who
|
|
||||||
committed the violation may be banned immediately, without warning.
|
|
||||||
3. Otherwise, moderators will first respond to such behavior with a warning.
|
|
||||||
4. Moderators follow a soft "three strikes" policy - the community member may
|
|
||||||
be given another chance, if they are receptive to the warning and change their
|
|
||||||
behavior.
|
|
||||||
5. If the community member is unreceptive or unreasonable when warned by a
|
|
||||||
moderator, or the warning goes unheeded, they may be banned for a first or
|
|
||||||
second offense. Repeated offenses will result in the community member being
|
|
||||||
banned.
|
|
||||||
|
|
||||||
## Scope
|
|
||||||
|
|
||||||
This Code of Conduct and the enforcement policies listed above apply to all
|
|
||||||
Adafruit Community venues. This includes but is not limited to any community
|
|
||||||
spaces (both public and private), the entire Adafruit Discord server, and
|
|
||||||
Adafruit GitHub repositories. Examples of Adafruit Community spaces include
|
|
||||||
but are not limited to meet-ups, audio chats on the Adafruit Discord, or
|
|
||||||
interaction at a conference.
|
|
||||||
|
|
||||||
This Code of Conduct applies both within project spaces and in public spaces
|
|
||||||
when an individual is representing the project or its community. As a community
|
|
||||||
member, you are representing our community, and are expected to behave
|
|
||||||
accordingly.
|
|
||||||
|
|
||||||
## Attribution
|
|
||||||
|
|
||||||
This Code of Conduct is adapted from the [Contributor Covenant][homepage],
|
|
||||||
version 1.4, available at
|
|
||||||
<https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>,
|
|
||||||
and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html).
|
|
||||||
|
|
||||||
For other projects adopting the Adafruit Community Code of
|
|
||||||
Conduct, please contact the maintainers of those projects for enforcement.
|
|
||||||
If you wish to use this code of conduct for your own project, consider
|
|
||||||
explicitly mentioning your moderation policy or making a copy with your
|
|
||||||
own moderation policy so as to avoid confusion.

This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor
|
|
||||||
|
|
||||||
Designed specifically to work with the Adafruit BME280 Breakout
|
|
||||||
* http://www.adafruit.com/products/2652

This is an example for how to use Adafruit_BusIO_RegisterBits from Adafruit_BusIO library.
|
|
||||||
|
|
||||||
Designed specifically to work with the Adafruit RTD Sensor

|
||||||
----> https://datasheets.maximintegrated.com/en/ds/MAX31865.pdf
|
|
||||||
|
|
||||||
This sensor uses SPI to communicate, 4 pins are required to
|
|
||||||
interface.
|
|
||||||
A fifth pin helps to detect when a new conversion is ready.

||||||
|
|
||||||
1. Definitions.

|
|
||||||
the copyright owner that is granting the License.
|
|
||||||
|
|
||||||
"Legal Entity" shall mean the union of the acting entity and all
|
|
||||||
other entities that control, are controlled by, or are under common
|
|
||||||
control with that entity. For the purposes of this definition,
|

||||||
"control" means (i) the power, direct or indirect, to cause the
|
|
||||||
direction or management of such entity, whether by contract or
|
|

otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
|
||||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
|
||||||
|
|
||||||
"You" (or "Your") shall mean an individual or Legal Entity
|
|
||||||
exercising permissions granted by this License.
|
|
||||||
|
|
||||||
"Source" form shall mean the preferred form for making modifications,

|
||||||
"Object" form shall mean any form resulting from mechanical
|
|
||||||
transformation or translation of a Source form, including but
|
|
||||||
not limited to compiled object code, generated documentation,
|
|
||||||
and conversions to other media types.
|
|
||||||
|
|
||||||
"Work" shall mean the work of authorship, whether in Source or
|
|
||||||
Object form, made available under the License, as indicated by a
|
|
||||||
copyright notice that is included in or attached to the work
|
|
||||||
(an example is provided in the Appendix below).
|
|
||||||
|
|
||||||
"Derivative Works" shall mean any work, whether in Source or Object
|
|
||||||
form, that is based on (or derived from) the Work and for which the
|
|
||||||
editorial revisions, annotations, elaborations, or other modifications
|
|
||||||
represent, as a whole, an original work of authorship. For the purposes
|
|
||||||
of this License, Derivative Works shall not include works that remain
|
|
||||||
separable from, or merely link (or bind by name) to the interfaces of,
|
|
||||||
the Work and Derivative Works thereof.
|
|
||||||
|
|
||||||
"Contribution" shall mean any work of authorship, including
|
|
||||||
the original version of the Work and any modifications or additions
|
|
||||||
to that Work or Derivative Works thereof, that is intentionally
|
|
||||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
|
||||||
or by an individual or Legal Entity authorized to submit on behalf of
|
|
||||||
the copyright owner. For the purposes of this definition, "submitted"
|
|
||||||
means any form of electronic, verbal, or written communication sent
|
|
||||||
to the Licensor or its representatives, including but not limited to
|
|
||||||
communication on electronic mailing lists, source code control systems,
|
|
||||||
and issue tracking systems that are managed by, or on behalf of, the
|
|
||||||
Licensor for the purpose of discussing and improving the Work, but
|
|
||||||
excluding communication that is conspicuously marked or otherwise
|
|
||||||
designated in writing by the copyright owner as "Not a Contribution."
|
|
||||||
|
|
||||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
|
||||||
on behalf of whom a Contribution has been received by Licensor and
|
|
||||||
subsequently incorporated within the Work.

||||||
|
|
||||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
copyright license to reproduce, prepare Derivative Works of,
|
|
||||||
publicly display, publicly perform, sublicense, and distribute the
|
|
||||||
Work and such Derivative Works in Source or Object form.
|
|
||||||
|
|
||||||
3. Grant of Patent License. Subject to the terms and conditions of
|
|
||||||
this License, each Contributor hereby grants to You a perpetual,
|
|
||||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
||||||
(except as stated in this section) patent license to make, have made,
|
|
||||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
||||||
where such license applies only to those patent claims licensable
|
|
||||||
by such Contributor that are necessarily infringed by their
|
|
||||||
Contribution(s) alone or by combination of their Contribution(s)
|
|
||||||
with the Work to which such Contribution(s) was submitted. If You
|
|
||||||
institute patent litigation against any entity (including a
|
|
||||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
||||||
or a Contribution incorporated within the Work constitutes direct
|
|
||||||
or contributory patent infringement, then any patent licenses
|
|
||||||
granted to You under this License for that Work shall terminate
|
|
||||||
as of the date such litigation is filed.
|
|
||||||
|
|
||||||
4. Redistribution. You may reproduce and distribute copies of the
|
|
||||||
Work or Derivative Works thereof in any medium, with or without
|
|
||||||
modifications, and in Source or Object form, provided that You
|
|
||||||
meet the following conditions:
|
|
||||||
|
|
||||||
(a) You must give any other recipients of the Work or
|
|
||||||
Derivative Works a copy of this License; and
|
|
||||||
|
|
||||||
(b) You must cause any modified files to carry prominent notices
|
|
||||||
stating that You changed the files; and
|
|
||||||
|
|
||||||
(c) You must retain, in the Source form of any Derivative Works
|
|
||||||
that You distribute, all copyright, patent, trademark, and
|
|
||||||
attribution notices from the Source form of the Work,
|
|
||||||
excluding those notices that do not pertain to any part of
|
|
||||||
the Derivative Works; and
|
|
||||||
|
|
||||||
(d) If the Work includes a "NOTICE" text file as part of its
|
|
||||||
distribution, then any Derivative Works that You distribute must
|
|
||||||
include a readable copy of the attribution notices contained
|
|
||||||
within such NOTICE file, excluding those notices that do not
|
|
||||||
pertain to any part of the Derivative Works, in at least one
|
|
||||||
of the following places: within a NOTICE text file distributed
|
|
||||||
as part of the Derivative Works; within the Source form or
|
|
||||||
documentation, if provided along with the Derivative Works; or,
|
|
||||||
within a display generated by the Derivative Works, if and
|
|
||||||
wherever such third-party notices normally appear. The contents
|
|
||||||
of the NOTICE file are for informational purposes only and
|
|
||||||
do not modify the License. You may add Your own attribution
|
|
||||||
notices within Derivative Works that You distribute, alongside
|
|
||||||
or as an addendum to the NOTICE text from the Work, provided
|
|
||||||
that such additional attribution notices cannot be construed
|
|
||||||
as modifying the License.
|
|
||||||
|
|
||||||
You may add Your own copyright statement to Your modifications and
|
|
||||||
may provide additional or different license terms and conditions
|
|
||||||
for use, reproduction, or distribution of Your modifications, or
|
|
||||||
for any such Derivative Works as a whole, provided Your use,
|
|
||||||
reproduction, and distribution of the Work otherwise complies with
|
|
||||||
the conditions stated in this License.
|
|
||||||
|
|
||||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
||||||
any Contribution intentionally submitted for inclusion in the Work
|
|
||||||
by You to the Licensor shall be under the terms and conditions of
|
|
||||||
this License, without any additional terms or conditions.
|
|
||||||
Notwithstanding the above, nothing herein shall supersede or modify
|
|
||||||
the terms of any separate license agreement you may have executed
|
|
||||||
with Licensor regarding such Contributions.
|
|
||||||
|
|
||||||
6. Trademarks. This License does not grant permission to use the trade
|
|
||||||
names, trademarks, service marks, or product names of the Licensor,
|
|
||||||
except as required for reasonable and customary use in describing the
|
|
||||||
origin of the Work and reproducing the content of the NOTICE file.
|
|
||||||
|
|
||||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
||||||
agreed to in writing, Licensor provides the Work (and each
|
|
||||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
||||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
||||||
implied, including, without limitation, any warranties or conditions
|
|
||||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
||||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
||||||
appropriateness of using or redistributing the Work and assume any
|
|
||||||
risks associated with Your exercise of permissions under this License.
|
|
||||||
|
|
||||||
8. Limitation of Liability. In no event and under no legal theory,
|
|
||||||
whether in tort (including negligence), contract, or otherwise,
|
|
||||||
unless required by applicable law (such as deliberate and grossly
|
|
||||||
negligent acts) or agreed to in writing, shall any Contributor be
|
|
||||||
liable to You for damages, including any direct, indirect, special,
|
|
||||||
incidental, or consequential damages of any character arising as a
|
|
||||||
result of this License or out of the use or inability to use the
|
|
||||||
Work (including but not limited to damages for loss of goodwill,
|
|
||||||
work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses), even if such Contributor
|
|
||||||
has been advised of the possibility of such damages.
|
|
||||||
|
|
||||||
9. Accepting Warranty or Additional Liability. While redistributing
|
|
||||||
the Work or Derivative Works thereof, You may choose to offer,
|
|
||||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
||||||
or other liability obligations and/or rights consistent with this
|
|
||||||
License. However, in accepting such obligations, You may act only
|
|
||||||
on Your own behalf and on Your sole responsibility, not on behalf
|
|
||||||
of any other Contributor, and only if You agree to indemnify,
|
|
||||||
defend, and hold each Contributor harmless for any liability
|
|
||||||
incurred by, or claims asserted against, such Contributor by reason
|
|
||||||
of your accepting any such warranty or additional liability.

# Adafruit Unified Sensor Driver #
|
|
||||||
|
|
||||||
Many small embedded systems exist to collect data from sensors, analyse the data, and either take an appropriate action or send that sensor data to another system for processing.
|
|
||||||
|
|
||||||
One of the many challenges of embedded systems design is the fact that parts you used today may be out of production tomorrow, or system requirements may change and you may need to choose a different sensor down the road.
|
|
||||||
|
|
||||||
Creating new drivers is a relatively easy task, but integrating them into existing systems is both error prone and time consuming since sensors rarely use the exact same units of measurement.
|
|
||||||
|
|
||||||
By reducing all data to a single **sensors\_event\_t** 'type' and settling on specific, **standardised SI units** for each sensor family the same sensor types return values that are comparable with any other similar sensor. This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability and code reuse.
|
|
||||||
|
|
||||||
The unified sensor abstraction layer is also useful for data-logging and data-transmission since you only have one well-known type to log or transmit over the air or wire.
|
|
||||||
|
|
||||||
## Unified Sensor Drivers ##
|
|
||||||

|
||||||

|
|
||||||
|
|
||||||
|
|
||||||
## How Does it Work? ##
|
|
||||||
|
|
||||||
Any driver that supports the Adafruit unified sensor abstraction layer will implement the Adafruit\_Sensor base class. There are two main typedefs and one enum defined in Adafruit_Sensor.h that are used to 'abstract' away the sensor details and values:
|
|
||||||
|
|
||||||
## Sensor Types (`sensors_type_t`)
|
|
||||||
|
|
||||||
These pre-defined sensor types are used to properly handle the two related typedefs below, and allows us determine what types of units the sensor uses, etc.
|
|
||||||
|
|
||||||
```c++
|
|
||||||
/** Sensor types */
|
|
||||||
typedef enum
|
|
||||||
{
|
|
||||||
SENSOR_TYPE_ACCELEROMETER = (1),
|
|
||||||
SENSOR_TYPE_MAGNETIC_FIELD = (2),
|
|
||||||
SENSOR_TYPE_ORIENTATION = (3),
|
|
||||||
SENSOR_TYPE_GYROSCOPE = (4),
|
|
||||||
SENSOR_TYPE_LIGHT = (5),
|
|
||||||
SENSOR_TYPE_PRESSURE = (6),
|
|
||||||
SENSOR_TYPE_PROXIMITY = (8),
|
|
||||||
SENSOR_TYPE_GRAVITY = (9),
|
|
||||||
SENSOR_TYPE_LINEAR_ACCELERATION = (10),
|
|
||||||
SENSOR_TYPE_ROTATION_VECTOR = (11),
|
|
||||||
SENSOR_TYPE_RELATIVE_HUMIDITY = (12),
|
|
||||||
SENSOR_TYPE_AMBIENT_TEMPERATURE = (13),
|
|
||||||
SENSOR_TYPE_VOLTAGE = (15),
|
|
||||||
SENSOR_TYPE_CURRENT = (16),
|
|
||||||
SENSOR_TYPE_COLOR = (17)
|
|
||||||
} sensors_type_t;
|
|
||||||
```
|
|
||||||
|
|
||||||
## Sensor Details (`sensor_t`)
|
|
||||||
|
|
||||||
This typedef describes the specific capabilities of this sensor, and allows us to know what sensor we are using beneath the abstraction layer.
|
|
||||||
|
|
||||||
```c++
|
|
||||||
/* Sensor details (40 bytes) */
|
|
||||||
/** struct sensor_s is used to describe basic information about a specific sensor. */
|
|
||||||
typedef struct
|
|
||||||
{
|
|
||||||
char name[12];
|
|
||||||
int32_t version;
|
|
||||||
int32_t sensor_id;
|
|
||||||
int32_t type;
|
|
||||||
float max_value;
|
|
||||||
float min_value;
|
|
||||||
float resolution;
|
|
||||||
int32_t min_delay;
|
|
||||||
} sensor_t;
|
|
||||||
```
|
|
||||||
|
|
||||||
The individual fields are intended to be used as follows:
|
|
||||||
|
|
||||||
- **name**: The sensor name or ID, up to a maximum of twelve characters (ex. "MPL115A2")
|
|
||||||
- **version**: The version of the sensor HW and the driver to allow us to differentiate versions of the board or driver
|
|
||||||
- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network
|
|
||||||
- **type**: The sensor type, based on **sensors\_type\_t** in sensors.h
|
|
||||||
- **max\_value**: The maximum value that this sensor can return (in the appropriate SI unit)
|
|
||||||
- **min\_value**: The minimum value that this sensor can return (in the appropriate SI unit)
|
|
||||||
- **resolution**: The smallest difference between two values that this sensor can report (in the appropriate SI unit)
|
|
||||||
- **min\_delay**: The minimum delay in microseconds between two sensor events, or '0' if there is no constant sensor rate
|
|
||||||
|
|
||||||
## Sensor Data/Events (`sensors_event_t`)
|
|
||||||
|
|
||||||
This typedef is used to return sensor data from any sensor supported by the abstraction layer, using standard SI units and scales.
|
|
||||||
|
|
||||||
```c++
|
|
||||||
/* Sensor event (36 bytes) */
|
|
||||||
/** struct sensor_event_s is used to provide a single sensor event in a common format. */
|
|
||||||
typedef struct
|
|
||||||
{
|
|
||||||
int32_t version;
|
|
||||||
int32_t sensor_id;
|
|
||||||
int32_t type;
|
|
||||||
int32_t reserved0;
|
|
||||||
int32_t timestamp;
|
|
||||||
union
|
|
||||||
{
|
|
||||||
float data[4];
|
|
||||||
sensors_vec_t acceleration;
|
|
||||||
sensors_vec_t magnetic;
|
|
||||||
sensors_vec_t orientation;
|
|
||||||
sensors_vec_t gyro;
|
|
||||||
float temperature;
|
|
||||||
float distance;
|
|
||||||
float light;
|
|
||||||
float pressure;
|
|
||||||
float relative_humidity;
|
|
||||||
float current;
|
|
||||||
float voltage;
|
|
||||||
sensors_color_t color;
|
|
||||||
};
|
|
||||||
} sensors_event_t;
|
|
||||||
```
|
|
||||||
It includes the following fields:
|
|
||||||
|
|
||||||
- **version**: Contain 'sizeof(sensors\_event\_t)' to identify which version of the API we're using in case this changes in the future
|
|
||||||
- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network (must match the sensor\_id value in the corresponding sensor\_t enum above!)
|
|
||||||
- **type**: the sensor type, based on **sensors\_type\_t** in sensors.h
|
|
||||||
- **timestamp**: time in milliseconds when the sensor value was read
|
|
||||||
- **data[4]**: An array of four 32-bit values that allows us to encapsulate any type of sensor data via a simple union (further described below)
|
|
||||||
|
|
||||||
## Required Functions
|
|
||||||
|
|
||||||
In addition to the two standard types and the sensor type enum, all drivers based on Adafruit_Sensor must also implement the following two functions:
|
|
||||||
|
|
||||||
```c++
|
|
||||||
bool getEvent(sensors_event_t*);
|
|
||||||
```
|
|
||||||
Calling this function will populate the supplied sensors\_event\_t reference with the latest available sensor data. You should call this function as often as you want to update your data.
|
|
||||||
|
|
||||||
```c++
|
|
||||||
void getSensor(sensor_t*);
|
|
||||||
```
|
|
||||||
Calling this function will provide some basic information about the sensor (the sensor name, driver version, min and max values, etc.
|
|
||||||
|
|
||||||
## Standardised SI values for `sensors_event_t`
|
|
||||||
|
|
||||||
A key part of the abstraction layer is the standardisation of values on SI units of a particular scale, which is accomplished via the data[4] union in sensors\_event\_t above. This 16 byte union includes fields for each main sensor type, and uses the following SI units and scales:
|
|
||||||
|
|
||||||
- **acceleration**: values are in **meter per second per second** (m/s^2)
|
|
||||||
- **magnetic**: values are in **micro-Tesla** (uT)
|
|
||||||
- **orientation**: values are in **degrees**
|
|
||||||
- **gyro**: values are in **rad/s**
|
|
||||||
- **temperature**: values in **degrees centigrade** (Celsius)
|
|
||||||
- **distance**: values are in **centimeters**
|
|
||||||
- **light**: values are in **SI lux** units
|
|
||||||
- **pressure**: values are in **hectopascal** (hPa)
|
|
||||||
- **relative\_humidity**: values are in **percent**
|
|
||||||
- **current**: values are in **milliamps** (mA)
|
|
||||||
- **voltage**: values are in **volts** (V)
|
|
||||||
- **color**: values are in 0..1.0 RGB channel luminosity and 32-bit RGBA format
|
|
||||||
|
|
||||||
## The Unified Driver Abstraction Layer in Practice ##
|
|
||||||
|
|
||||||
Using the unified sensor abstraction layer is relatively easy once a compliant driver has been created.
|
|
||||||
|
|
||||||
Every compliant sensor can now be read using a single, well-known 'type' (sensors\_event\_t), and there is a standardised way of interrogating a sensor about its specific capabilities (via sensor\_t).
|
|
||||||
|
|
||||||
An example of reading the [TSL2561](https://github.com/adafruit/Adafruit_TSL2561) light sensor can be seen below:
|
|
||||||
|
|
||||||
```c++
|
|
||||||
Adafruit_TSL2561 tsl = Adafruit_TSL2561(TSL2561_ADDR_FLOAT, 12345);
|
|
||||||
...
|
|
||||||
/* Get a new sensor event */
|
|
||||||
sensors_event_t event;
|
|
||||||
tsl.getEvent(&event);
|
|
||||||
|
|
||||||
/* Display the results (light is measured in lux) */
|
|
||||||
if (event.light)
|
|
||||||
{
|
|
||||||
Serial.print(event.light); Serial.println(" lux");
|
|
||||||
}
|
|
||||||
else
|
|
||||||
{
|
|
||||||
/* If event.light = 0 lux the sensor is probably saturated
|
|
||||||
and no reliable data could be generated! */
|
|
||||||
Serial.println("Sensor overload");
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Similarly, we can get the basic technical capabilities of this sensor with the following code:
|
|
||||||
|
|
||||||
```c++
|
|
||||||
sensor_t sensor;
|
|
||||||
|
|
||||||
sensor_t sensor;
|
|
||||||
tsl.getSensor(&sensor);
|
|
||||||
|
|
||||||
/* Display the sensor details */
|
|
||||||
Serial.println("------------------------------------");
|
|
||||||
Serial.print ("Sensor: "); Serial.println(sensor.name);
|
|
||||||
Serial.print ("Driver Ver: "); Serial.println(sensor.version);
|
|
||||||
Serial.print ("Unique ID: "); Serial.println(sensor.sensor_id);
|
|
||||||
Serial.print ("Max Value: "); Serial.print(sensor.max_value); Serial.println(" lux");
|
|
||||||
Serial.print ("Min Value: "); Serial.print(sensor.min_value); Serial.println(" lux");
|
|
||||||
Serial.print ("Resolution: "); Serial.print(sensor.resolution); Serial.println(" lux");
|
|
||||||
Serial.println("------------------------------------");
|
|
||||||
Serial.println("");
|
|
||||||
```

# Changelog
|
|
||||||
## 3.12.1 [2022-08-29]
|
|
||||||
### Fixes
|
|
||||||
- [193](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/193) - Automatically adjusting point timestamp according to the setting of write precision.
|
|
||||||
|
|
||||||
## 3.12.0 [2022-03-21]
|
|
||||||
### Features
|
|
||||||
- [185](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/185) - Added diagnostic server connection state getter `bool InfluxDBClient::isConnected()`
|
|
||||||
|
|
||||||
## 3.11.0 [2022-02-18]
|
|
||||||
### Features
|
|
||||||
- [174](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/174),[181](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/181) - All API methods with a string param allow specifying string by all basic types:
|
|
||||||
- Arduino `String` class
|
|
||||||
- C `char *` or `char[]`
|
|
||||||
- Flash string using `F`,`PSTR` or `FPSTR` macros
|
|
||||||
### Fixes
|
|
||||||
- [176](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/176) - Cleared all compiler warnings
|
|
||||||
|
|
||||||
## 3.10.0 [2022-01-20]
|
|
||||||
### Features
|
|
||||||
- [167](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/167) - Added `InfluxDBClient::writeRecord(const char *record)`.
|
|
||||||
- [167](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/167) - Added possibility to disable retrying by setting `maxRetryAttempts` to zero: `client.setWriteOptions(WriteOptions().maxRetryAttempts(0));`
|
|
||||||
- [172](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/172) - Added directly streaming batch for write. It can be enabled by `InfluxDBClient::setStreamWrite(bool enable = true)`. Writing by streaming lines of batch saves RAM as it sends data without allocating a buffer. On the other hand, this way of writing is about half times slower than the classic way, when allocating the buffer for writing the whole batch.
|
|
||||||
- [172](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/172) - Allowing larger batch size, > 255.
|
|
||||||
- [173](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/173) - Added Flux query parameters. Now supported by InfluxDB Cloud only.

|
|
||||||
## 3.4.0 [2020-10-02]
|
|
||||||
### Features
|
|
||||||
- [#89](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/89) - ESP8266 only - Added Max Fragment Length Negotiation for TLS communication to reduce memory allocation. If server supports MFLN, it saves ~10kB. Standalone InfluxDB OSS server doesn't support MFLN, Cloud yes. To leverage MFLN for standalone OSS, a reverse proxy needs to be used.
|
|
||||||
- [#91](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/91) - Improved API for settings of write and HTTP options:
|
|
||||||
- Introduced `WriteOptions` to wrap the write related options (write precision, batch-size, etc). It offers fluent style API allowing to change only the required options. `InfluxDBClient` has overloaded `setWriteOptions(const WriteOptions& writeOptions)` method.
|
|
||||||
- Introduced `HTTPOptions` to wrap the HTTP related options (e.g. reusing connection). It offers fluent style API allowing to change only the required options. `InfluxDBClient` has `setHTTPOptions(const HTTPOptions& httpOptions)` method.
|
|
||||||
- Added possibility to set HTTP response read timeout (part of the `HTTPOptions`).
|
|
||||||
- Method `InfluxDBClient::void setWriteOptions(WritePrecision precision, uint16_t batchSize = 1, uint16_t bufferSize = 5, uint16_t flushInterval = 60, bool preserveConnection = true)` is deprecated and it will be removed in the next release.
|
|
||||||
- [#93](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/93) - Write logic improvements
|
|
||||||
- Retry on failure logic unification with other InfluxDB clients (exponential retry, max retry count 3, max retry interval)
|
|
||||||
- Better write buffer memory management
|
|
||||||
|
|
||||||
### Documentation

|
||||||
- [#87](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/87) - Fixed include file name in the Readme
|
|
||||||
- [#99](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/99) - Changed default InfluxDB 2 port from 9999 to 8086 (default since InfluxDB 2 RC0)
|
|
||||||
|
|
||||||
### Fixes

|
||||||
- [#90](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino/pull/90) - Fixed boolean type recognition of InfluxDB Flux
|
|
||||||

# InfluxDB Arduino Client
|
|
||||||
|
|
||||||
Simple Arduino client for writing and reading data from [InfluxDB](https://www.influxdata.com/products/influxdb-overview/), no matter whether it is a local server or InfluxDB Cloud. The library supports authentication, secure communication over TLS, [batching](#writing-in-batches), [automatic retrying](#buffer-handling-and-retrying) on server back-pressure and connection failure.
|
|
||||||
|
|
||||||
It also allows setting data in various formats, automatically escapes special characters and offers specifying timestamp in various precisions.
|
|
||||||
|
|
||||||
Library supports both [InfluxDB 2](#basic-code-for-influxdb-2) and [InfluxDB 1](#basic-code-for-influxdb-2).
|
|
||||||
|
|
||||||
This is a new implementation and the API, [original API](#original-api) is still supported.
|
|
||||||
|
|
||||||
Supported devices:
|
|
||||||
- ESP8266 with [Arduino core for ESP8266](https://github.com/esp8266/Arduino) at least version [3.0.2](https://github.com/esp8266/Arduino/releases/tag/3.0.2).
|
|
||||||
- ESP32 with [Arduino core for the ESP32](https://github.com/espressif/arduino-esp32) at least version [2.0.2](https://github.com/espressif/arduino-esp32/releases/tag/2.0.2).
|
|
||||||
|
|
||||||
This library doesn't support using those devices as a peripheral.
|
|
||||||
|
|
||||||
:warning: Only connection over internal WiFi capability is supported for now.

## Basic code for InfluxDB 2
|
|
||||||
After [setting up an InfluxDB 2 server](https://docs.influxdata.com/influxdb/v2.0/get-started/), first define connection parameters and a client instance:
|
|
||||||
```cpp
|
|
||||||
// InfluxDB 2 server url, e.g. http://192.168.1.48:8086 (Use: InfluxDB UI -> Load Data -> Client Libraries)
|
|
||||||
#define INFLUXDB_URL "influxdb-url"
|
|
||||||
// InfluxDB 2 server or cloud API authentication token (Use: InfluxDB UI -> Load Data -> Tokens -> <select token>)
|
|
||||||
#define INFLUXDB_TOKEN "token"
|
|
||||||
// InfluxDB 2 organization name or id (Use: InfluxDB UI -> Settings -> Profile -> <name under tile> )
|
|
||||||
#define INFLUXDB_ORG "org"
|
|
||||||
// InfluxDB 2 bucket name (Use: InfluxDB UI -> Load Data -> Buckets)
|
|
||||||
#define INFLUXDB_BUCKET "bucket"
|
|
||||||
|
|
||||||
// Single InfluxDB instance
|
|
||||||
InfluxDBClient client(INFLUXDB_URL, INFLUXDB_ORG, INFLUXDB_BUCKET, INFLUXDB_TOKEN);
|
|
||||||
```
|
|
||||||
|
|
||||||
The next step is adding data. A single row of data is represented by the `Point` class. It consists of a measurement name (like a table name), tags (which labels data) and fields ( the values to store):
|
|
||||||
```cpp
|
|
||||||
// Define data point in the measurement named 'device_status`
|
|
||||||
Point pointDevice("device_status");
|
|
||||||
// Set tags
|
|
||||||
pointDevice.addTag("device", "ESP8266");
|
|
||||||
pointDevice.addTag("SSID", WiFi.SSID());
|
|
||||||
// Add data fields
|
|
||||||
pointDevice.addField("rssi", WiFi.RSSI());
|
|
||||||
pointDevice.addField("uptime", millis());
|
|
||||||
```
|
|
||||||
|
|
||||||
And finally, write the data to the database:
|
|
||||||
```cpp
|
|
||||||
// Write data
|
|
||||||
client.writePoint(pointDevice);
|
|
||||||
```
|
|
||||||
|
|
||||||
Complete source code is available in the [BasicWrite example](examples/BasicWrite/BasicWrite.ino).
|
|
||||||
|
|
||||||
Data can be seen in the InfluxDB UI immediately. Use the [Data Explorer](https://docs.influxdata.com/influxdb/v2.0/query-data/execute-queries/data-explorer/) or create a [Dashboard](https://docs.influxdata.com/influxdb/v2.0/visualize-data/dashboards/).
|
|
||||||
|
|
||||||
## Basic code for InfluxDB 1
|
|
||||||
Using InfluxDB Arduino client for InfluxDB 1 is almost the same as for InfluxDB 2. The only difference is that InfluxDB 1 uses _database_ as classic name for data storage instead of bucket and the server is unsecured by default.
|
|
||||||
There is also a different `InfluxDBClient constructor` and `setConnectionParametersV1` function for setting the security params. Everything else remains the same.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// InfluxDB server url, e.g. http://192.168.1.48:8086 (don't use localhost, always server name or ip address)
|
|
||||||
#define INFLUXDB_URL "influxdb-url"
|
|
||||||
// InfluxDB database name
|
|
||||||
#define INFLUXDB_DB_NAME "database"
|
|
||||||
|
|
||||||
// Single InfluxDB instance
|
|
||||||
InfluxDBClient client(INFLUXDB_URL, INFLUXDB_DB_NAME);
|
|
||||||
|
|
||||||
// Define data point with measurement name 'device_status`
|
|
||||||
Point pointDevice("device_status");
|
|
||||||
// Set tags
|
|
||||||
pointDevice.addTag("device", "ESP8266");
|
|
||||||
pointDevice.addTag("SSID", WiFi.SSID());
|
|
||||||
// Add data
|
|
||||||
pointDevice.addField("rssi", WiFi.RSSI());
|
|
||||||
pointDevice.addField("uptime", millis());
|
|
||||||
|
|
||||||
// Write data
|
|
||||||
client.writePoint(pointDevice);
|
|
||||||
```
|
|
||||||
|
|
||||||
Complete source code is available in [BasicWrite example](examples/BasicWrite/BasicWrite.ino)
|
|
||||||
|
|
||||||
## Connecting to InfluxDB Cloud 2
|
|
||||||
Instead of setting up a local InfluxDB 2 server, it is possible to quickly [start with InfluxDB Cloud 2](https://docs.influxdata.com/influxdb/cloud/get-started/) with a [Free Plan](https://docs.influxdata.com/influxdb/cloud/account-management/pricing-plans/#free-plan).
|
|
||||||
|
|
||||||
InfluxDB Cloud uses secure communication over TLS (https). We need to tell the client to trust this connection. The paragraph bellow describes how to set trusted connection. However, InfluxDB cloud servers have only 3 months validity period. Their CA certificate, included in this library, is valid until 2035. Check [Skipping certification validation](#skipping-certificate-validation) for more details.
|
|
||||||
|
|
||||||
Connecting an Arduino client to InfluxDB Cloud server requires a few additional steps comparing to connecting to local server.
|
|
||||||
|
|
||||||
Connection parameters are almost the same as above, the only difference is that server URL now points to the InfluxDB Cloud 2, you set up after you've finished creating an InfluxDB Cloud 2 subscription. You will find the correct server URL in `InfluxDB UI -> Load Data -> Client Libraries`.
|
|
||||||
```cpp
|
|
||||||
//Include also InfluxCloud 2 CA certificate
|
|
||||||
#include <InfluxDbCloud.h>
|
|
||||||
// InfluxDB 2 server or cloud url, e.g. https://eu-central-1-1.aws.cloud2.influxdata.com (Use: InfluxDB UI -> Load Data -> Client Libraries)
|
|
||||||
#define INFLUXDB_URL "influxdb-url"
|
|
||||||
// InfluxDB 2 server or cloud API authentication token (Use: InfluxDB UI -> Load Data -> Tokens -> <select token>)
|
|
||||||
#define INFLUXDB_TOKEN "token"
|
|
||||||
// InfluxDB 2 organization name or id (Use: InfluxDB UI -> Settings -> Profile -> <name under tile> )
|
|
||||||
#define INFLUXDB_ORG "org"
|
|
||||||
// InfluxDB 2 bucket name (Use: InfluxDB UI -> Load Data -> Buckets)
|
|
||||||
#define INFLUXDB_BUCKET "bucket"
|
|
||||||
```
|
|
||||||
|
|
||||||
You need to pass an additional parameter to the client constructor, which is a certificate of the server to trust. The constant `InfluxDbCloud2CACert` contains the InfluxDB Cloud 2 CA certificate, which is predefined in this library:
|
|
||||||
```cpp
|
|
||||||
// Single InfluxDB instance
|
|
||||||
InfluxDBClient client(INFLUXDB_URL, INFLUXDB_ORG, INFLUXDB_BUCKET, INFLUXDB_TOKEN, InfluxDbCloud2CACert);
|
|
||||||
```
|
|
||||||
Read more about [secure connection](#secure-connection).
|
|
||||||
|
|
||||||
Additionally, time needs to be synced:
|
|
||||||
```cpp
|
|
||||||
// Synchronize time with NTP servers and set timezone
|
|
||||||
// Accurate time is necessary for certificate validation and writing in batches
|
|
||||||
// For the fastest time sync find NTP servers in your area: https://www.pool.ntp.org/zone/
|
|
||||||
configTzTime(TZ_INFO "pool.ntp.org", "time.nis.gov");
|
|
||||||
```
|
|
||||||
Read more about time synchronization in [Configure Time](#configure-time).
|
|
||||||
|
|
||||||
Defining data and writing it to the DB is the same as in the case of [BasicWrite](#basic-code):
|
|
||||||
```cpp
|
|
||||||
// Define data point with measurement name 'device_status`
|
|
||||||
Point pointDevice("device_status");
|
|
||||||
// Set tags
|
|
||||||
pointDevice.addTag("device", "ESP8266");
|
|
||||||
pointDevice.addTag("SSID", WiFi.SSID());
|
|
||||||
// Add data
|
|
||||||
pointDevice.addField("rssi", WiFi.RSSI());
|
|
||||||
pointDevice.addField("uptime", millis());
|
|
||||||
|
|
||||||
// Write data
|
|
||||||
client.writePoint(pointDevice);
|
|
||||||
```
|
|
||||||
Complete source code is available in [SecureWrite example](examples/SecureWrite/SecureWrite.ino).
|
|
||||||
|
|
||||||
## Writing in Batches
|
|
||||||
InfluxDB client for Arduino can also write data in batches. A batch is simply a set of points that will be sent at once. To create a batch, the client will keep all points until the number of points reaches the batch size and then it will write all points at once to the InfluxDB server. This is often more efficient than writing each point separately.
|
|
||||||
|
|
||||||
### Timestamp
|
|
||||||
If using batch writes, the timestamp should be employed. Timestamp specifies the time when data was gathered and it is used in the form of a number of seconds (milliseconds, etc) from epoch (1.1.1970) UTC.
|
|
||||||
If points have no timestamp assigned, InfluxDB assigns a timestamp at the time of writing, which could happen much later than the data has been obtained, because the final batch write will happen when the batch is full (or when [flush buffer](#buffer-handling-and-retrying) is forced).
|
|
||||||
|
|
||||||
InfluxDB allows sending timestamps in various precisions - nanoseconds, microseconds, milliseconds or seconds. The milliseconds precision is usually enough for using on Arduino. The maximum available precision is microseconds. Setting the timestamp to nanoseconds will just add zeroes for microseconds fraction and will not improve timestamp accuracy.
|
|
||||||
|
|
||||||
The client has to be configured with a time precision. The default settings is to not use the timestamp, which means that the server will assign a timestamp when the data is written to the database. The `setWriteOptions` functions allows setting custom `WriteOptions` params and one of them is __write precision__:
|
|
||||||
``` cpp
|
|
||||||
// Set write precision to milliseconds. Leave other parameters default.
|
|
||||||
client.setWriteOptions(WriteOptions().writePrecision(WritePrecision::MS));
|
|
||||||
```
|
|
||||||
When a write precision is configured, the client will automatically assign the current time to the timestamp of each written point which doesn't have a timestamp assigned.
|
|
||||||
|
|
||||||
If you want to manage timestamp on your own, there are several ways to set the timestamp explicitly.
|
|
||||||
- `setTime(WritePrecision writePrecision)` - Sets the timestamp to the actual time in the desired precision. The same precision must set in WriteOptions.
|
|
||||||
- `setTime(unsigned long long timestamp)` - Sets the timestamp to an offset since the epoch. Correct precision must be set InfluxDBClient::setWriteOptions.
|
|
||||||
- `setTime(String timestamp)` - Sets the timestamp to an offset since the epoch. Correct precision must be set InfluxDBClient::setWriteOptions.
|
|
||||||
|
|
||||||
The `getTime()` method allows copying the timestamp between points.
|
|
||||||
|
|
||||||
|
|
||||||
### Configure Time
|
|
||||||
Dealing with timestamps, and also validating server or CA certificate, requires that the device has correctly set the time. This can be done with one line of code:
|
|
||||||
```cpp
|
|
||||||
// Synchronize time with NTP servers and set timezone
|
|
||||||
// Accurate time is necessary for certificate validation and writing in batches
|
|
||||||
// For the fastest time sync find NTP servers in your area: https://www.pool.ntp.org/zone/
|
|
||||||
configTzTime("PST8PDT", "pool.ntp.org", "time.nis.gov");
|
|
||||||
```
|
|
||||||
The `configTzTime` function starts the time synchronization with NTP servers. The first parameter specifies the timezone information, which is important for distinguishing between UTC and a local timezone and for daylight saving changes.
|
|
||||||
The last two string parameters are the internet addresses of NTP servers. Check [pool.ntp.org](https://www.pool.ntp.org/zone) for address of some local NTP servers.
|
|
||||||
|
|
||||||
Timezone string details are described at [https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html](https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html).
|
|
||||||
Values for some timezones:
|
|
||||||
- Central Europe: `CET-1CEST,M3.5.0,M10.5.0/3`
|
|
||||||
- Eastern: `EST5EDT`
|
|
||||||
- Japanese: `JST-9`
|
|
||||||
- Pacific Time: `PST8PDT`
|
|
||||||
|
|
||||||
There is also another function for syncing the time, which takes timezone and DST offset. As DST info is set via static offset it will create local time problem when DST change occurs.
|
|
||||||
It's declaration is following:
|
|
||||||
```cpp
|
|
||||||
configTime(long gmtOffset_sec, int daylightOffset_sec, const char* server1, const char* server2 = nullptr, const char* server3 = nullptr);
|
|
||||||
```
|
|
||||||
|
|
||||||
In the example code it would be:
|
|
||||||
```cpp
|
|
||||||
// Synchronize time with NTP servers
|
|
||||||
// Accurate time is necessary for certificate validation and writing in batches
|
|
||||||
configTime(3600, 3600, "pool.ntp.org", "time.nis.gov");
|
|
||||||
```
|
|
||||||
|
|
||||||
Both `configTzTime` and `configTime` functions are asynchronous. This means that calling the functions just starts the time synchronization. Time is often not synchronized yet upon returning from call.
|
|
||||||
|
|
||||||
There is a helper function `timeSync` provided with the this library. The function starts time synchronization by calling the `configTzTime` and waits maximum 20 seconds for time to be synchronized. It prints progress info and final local time to the `Serial` console.
|
|
||||||
`timeSync` has the same signature as `configTzTime` and it is included with the main header file `InfluxDbClient.h`:
|
|
||||||
```cpp
|
|
||||||
// Synchronize time with NTP servers and waits for competition. Prints waiting progress and final synchronized time to the Serial.
|
|
||||||
// Accurate time is necessary for certificate validation and writing points in batch
|
|
||||||
// For the fastest time sync find NTP servers in your area: https://www.pool.ntp.org/zone/
|
|
||||||
void timeSync(const char *tzInfo, const char* ntpServer1, const char* ntpServer2 = nullptr, const char* ntpServer3 = nullptr);
|
|
||||||
```
|
|
||||||
|
|
||||||
### Batch Size
|
|
||||||
Setting batch size depends on data gathering and DB updating strategy.
|
|
||||||
|
|
||||||
If data is written in short periods (seconds), the batch size should be set according to your expected write periods and update frequency requirements.
|
|
||||||
For example, if you would like to see updates (on the dashboard or in processing) each minute and you are measuring a single value (1 point) every 10s (6 points per minute), the batch size should be 6. If it is sufficient to update each hour and you are creating 1 point each minute, your batch size should be 60.
|
|
||||||
|
|
||||||
In cases where the data should be written in longer periods and gathered data consists of several points, the batch size should be set to the expected number of points to be gathered.
|
|
||||||
|
|
||||||
To set the batch size we use `WriteOptions` object and [setWriteOptions](#write-options) function:
|
|
||||||
```cpp
|
|
||||||
// Enable lines batching
|
|
||||||
client.setWriteOptions(WriteOptions().batchSize(10));
|
|
||||||
```
|
|
||||||
Writing the point will add a point to the underlying buffer until the batch size is reached:
|
|
||||||
```cpp
|
|
||||||
// Write first point to the buffer
|
|
||||||
// Buffered write always returns `true`
|
|
||||||
client.writePoint(point1);
|
|
||||||
// Write second point to the buffer
|
|
||||||
client.writePoint(point2);
|
|
||||||
..
|
|
||||||
// Write ninth point to the buffer
|
|
||||||
client.writePoint(point9);
|
|
||||||
// Writing tenth point will cause flushing buffer and returns actual write result.
|
|
||||||
if(!client.writePoint(point10)) {
|
|
||||||
Serial.print("InfluxDB write failed: ");
|
|
||||||
Serial.println(client.getLastErrorMessage());
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
In case cases where the number of points is not always the same, set the batch size to the maximum number of points and use the `flushBuffer()` function to force writing to the database. See [Buffer Handling](#buffer-handling-and-retrying) for more details.
|
|
||||||
|
|
||||||
### Large batch size
|
|
||||||
The maximum batch size depends on the available RAM of the device (~45KB for ESP8266 and ~260KB for ESP32). Larger batch size, >100 for ESP8255, >2000 for ESP32, must be chosen carefully to not crash the app with out of memory error. The Stream write mode must be used, see [Write Modes](#write-modes)
|
|
||||||
|
|
||||||
Always determine your typical line length using `client.pointToLineProtocol(point).length()`. For example, ESP32 can handle 2048 lines with an average length of 69. When the length of line or batch size is increased, the device becomes unstable, even there is more than 76k, it cannot send data or even crashes. ESP8266 handles successfully 330 of such lines.
|
|
||||||
|
|
||||||
:warning: Thoroughly test your app when using large batch files.
|
|
||||||
|
|
||||||
### Write Modes
|
|
||||||
Client has two modes of writing:
|
|
||||||
- Buffer (default)
|
|
||||||
- Stream
|
|
||||||
|
|
||||||
Writing is performed the way that client keeps written lines (points) separately and when a batch is completed, it allocates a data buffer for sending to a server via WiFi Client.
|
|
||||||
This is the fastest way to write data but requires some amount of free memory. Thus a big batch size cannot be used.
|
|
||||||
|
|
||||||
Another way of writing is *stream write*.
|
|
||||||
```cpp
|
|
||||||
// Enables stream write
|
|
||||||
client.setStreamWrite(true);
|
|
||||||
```
|
|
||||||
In this mode client continuously streams lines from batch to WiFi Client. No buffer allocation. As lines are allocated separately, it avoids problems with max allocable block size. The downside is, that writing is about 50% slower than in the Buffer mode.
|
|
||||||
|
|
||||||
## Buffer Handling and Retrying
|
|
||||||
InfluxDB contains an underlying buffer for handling writing in batches and automatic retrying on server back-pressure and connection failure.
|
|
||||||
|
|
||||||
Its size is controlled by the `bufferSize` param of [WriteOptions](#write-options) object:
|
|
||||||
```cpp
|
|
||||||
// Increase buffer to allow caching of failed writes
|
|
||||||
client.setWriteOptions(WriteOptions().bufferSize(50));
|
|
||||||
```
|
|
||||||
The recommended size is at least 2 x batch size.
|
|
||||||
|
|
||||||
The state of the buffer can be determined via two functions:
|
|
||||||
- `isBufferEmpty()` - Returns true if buffer is empty
|
|
||||||
- `isBufferFull()` - Returns true if buffer is full
|
|
||||||
|
|
||||||
A full buffer can occur when there is a problem with the internet connection or the InfluxDB server is overloaded. In such cases, points to write remain in the buffer. When more points are added and connection problem remains, the buffer will reach the top and new points will overwrite older points.
|
|
||||||
|
|
||||||
Each attempt to write a point will try to send older points in the buffer. So, the `isBufferFull()` function can be used to skip low priority points.
|
|
||||||
|
|
||||||
The `flushBuffer()` function can be used to force writing, even if the number of points in the buffer is lower than the batch size. With the help of the `isBufferEmpty()` function a check can be made before a device goes to sleep:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// Check whether buffer in not empty
|
|
||||||
if (!client.isBufferEmpty()) {
|
|
||||||
// Write all remaining points to db
|
|
||||||
client.flushBuffer();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Other functions for dealing with buffer:
|
|
||||||
- `checkBuffer()` - Checks point buffer status and flushes if the number of points reaches batch size or flush interval runs out. This is the main function for controlling the buffer and it is used internally.
|
|
||||||
- `resetBuffer()` - Clears the buffer.
|
|
||||||
|
|
||||||
Check [SecureBatchWrite example](examples/SecureBatchWrite/SecureBatchWrite.ino) for example code of buffer handling functions.
|
|
||||||
|
|
||||||
## Write Options
|
|
||||||
Writing points can be controlled via `WriteOptions`, which is set in the `setWriteOptions` function:
|
|
||||||
|
|
||||||
| Parameter | Default Value | Meaning |
|
|
||||||
|-----------|---------------|---------|
|
|
||||||
| writePrecision | `WritePrecision::NoTime` | Timestamp precision of written data |
|
|
||||||
| batchSize | `1` | Number of points that will be written to the database at once |
|
|
||||||
| bufferSize | `5` | Maximum number of points in buffer. Buffer contains new data that will be written to the database and also data that failed to be written due to network failure or server overloading |
|
|
||||||
| flushInterval | `60` | Maximum time(in seconds) data will be held in buffer before points are written to the db |
|
|
||||||
| retryInterval | `5` | Default retry interval in sec, if not sent by server. Value `0` disables retrying |
|
|
||||||
| maxRetryInterval | `300` | Maximum retry interval in sec |
|
|
||||||
| maxRetryAttempts | `3` | Maximum count of retry attempts of failed writes |
|
|
||||||
|
|
||||||
## HTTP Options
|
|
||||||
`HTTPOptions` controls some aspects of HTTP communication and they are set via `setHTTPOptions` function:
|
|
||||||
| Parameter | Default Value | Meaning |
|
|
||||||
|-----------|---------------|---------|
|
|
||||||
| connectionReuse | `false` | Whether HTTP connection should be kept open after initial communication. Usable for frequent writes/queries. |
|
|
||||||
| httpReadTimeout | `5000` | Timeout (ms) for reading server response |
|
|
||||||
|
|
||||||
## Secure Connection
|
|
||||||
Connecting to a secured server requires configuring the client to trust the server. This is achieved by providing the client with a server certificate, certificate authority certificate or certificate SHA1 fingerprint.
|
|
||||||
|
|
||||||
:memo: In ESP32 arduino SDK (1.0.4), `WiFiClientSecure` doesn't support fingerprint to validate the server certificate.
|
|
||||||
|
|
||||||
The certificate (in PEM format) or SHA1 fingerprint should be placed in flash memory to save RAM.
|
|
||||||
Code bellow is an example certificate in PEM format. Valid InfluxDB 2 Cloud CA certificate is included in the library in the constant `InfluxDbCloud2CACert`, located in the `InfluxDBCloud.h`.
|
|
||||||
|
|
||||||
You can use a custom server certificate by exporting it, e.g. using a web browser:
|
|
||||||
```cpp
|
|
||||||
// Server certificate in PEM format, placed in the program (flash) memory to save RAM
|
|
||||||
const char ServerCert[] PROGMEM = R"EOF(

const char ServerCert[] PROGMEM = "cabd2a79a1076a31f21d253635cb039d4329a5e8";
|
|
||||||
```
|
|
||||||
|
|
||||||
### InfluxDb 2
|
|
||||||
There are two ways to set the certificate or fingerprint to trust a server:
|
|
||||||
- Use full param constructor
|
|
||||||
```cpp
|
|
||||||
// InfluxDB client instance with preconfigured InfluxCloud certificate
|
|
||||||
InfluxDBClient client(INFLUXDB_URL, INFLUXDB_ORG, INFLUXDB_BUCKET, INFLUXDB_TOKEN, ServerCert);
|
|
||||||
```
|
|
||||||
- Use `setConnectionParams` function:
|
|
||||||
```cpp
|
|
||||||
// InfluxDB client instance
|
|
||||||
InfluxDBClient client;
|
|
||||||
|
|
||||||
void setup() {
|
|
||||||
// configure client
|
|
||||||
client.setConnectionParams(INFLUXDB_URL, INFLUXDB_ORG, INFLUXDB_BUCKET, INFLUXDB_TOKEN, ServerCert);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
### InfluxDb 1
|
|
||||||
|
|
||||||
Use `setConnectionParamsV1` function:
|
|
||||||
```cpp
|
|
||||||
// InfluxDB client instance
|
|
||||||
InfluxDBClient client;
|
|
||||||
|
|
||||||
void setup() {
|
|
||||||
// configure client
|
|
||||||
client.setConnectionParamsV1(INFLUXDB_URL, INFLUXDB_DATABASE, INFLUXDB_USER, INFLUXDB_PASSWORD, ServerCert);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
Another important prerequisite to successfully validate a server or CA certificate is to have properly synchronized time. More on this in [Configure Time](#configure-time).
|
|
||||||
|
|
||||||
:information_source: Time synchronization is not required for validating server certificate via SHA1 fingerprint.
|
|
||||||
|
|
||||||
### Skipping certificate validation
|
|
||||||
The CA certificate provided with the library is ISRG Root X1. This certificate lasts a very long time, until 2035. It is not necessary to update your device until then when using ISRG Root X1.
|
|
||||||
|
|
||||||
If you are using your own certificate, plase keep in mind server certificates have limited validity period, often only a few months. It will be necessary to frequently change trusted certificate in the source code and reflashing the device. A solution could be using OTA update, but you will still need to care about certificate validity and updating it ahead of time to avoid connection failures.
|
|
||||||
|
|
||||||
The best way to prevent frequent updates is to use a root certificate like the one provided with the library. If you are unable to use a root certificate from a trusted authority, you may want to use insecure mode instead. This is done with the help of `InfluxDBClient::setInsecure()` method.
|
|
||||||
You will also save space in flash (and RAM) by leaving certificate param empty when calling constructor or `setConnectionParams` method.
|
|
||||||
|
|
||||||
:memo: The `InfluxDBClient::setInsecure()` method must be called before calling any function that will establish connection. The best place to call it is in the `setup` method:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// InfluxDB client instance without a server certificate
|
|
||||||
InfluxDBClient client(INFLUXDB_URL, INFLUXDB_ORG, INFLUXDB_BUCKET, INFLUXDB_TOKEN);
|
|
||||||
|
|
||||||
void setup() {
|
|
||||||
// Set insecure connection to skip server certificate validation
|
|
||||||
client.setInsecure();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
:warning: Using untrusted connection is a security risk.
|
|
||||||
|
|
||||||
## Querying
|
|
||||||
InfluxDB 2 and InfluxDB 1.7+ (with [enabled flux](https://docs.influxdata.com/influxdb/latest/administration/config/#flux-enabled-false)) uses [Flux](https://www.influxdata.com/products/flux/) to process and query data. InfluxDB client for Arduino offers a simple, but powerful, way how to query data with `query` function. It parses response line by line, so it can read a huge responses (thousands data lines), without consuming a lot device memory.
|
|
||||||
|
|
||||||
The `query` returns `FluxQueryResult` object, which parses response and provides useful getters for accessing values from result set.
|
|
||||||
|
|
||||||
The InfluxDB flux query result set is returned in CSV format. In the example below, the first line contains type information and the second column names, and the rest is data:
|
|
||||||
```CSV
|
|
||||||
#datatype,string,long,dateTime:RFC3339,dateTime:RFC3339,dateTime:RFC3339,long,string,string,string,string

|
||||||

|
|
||||||

|
|
||||||
,_result,0,2020-05-18T15:06:00.475253281Z,2020-05-19T15:06:00.475253281Z,2020-05-19T13:08:07Z,-55,667G,rssi,wifi_status,ESP32
|
|
||||||
,_result,0,2020-05-18T15:06:00.475253281Z,2020-05-19T15:06:00.475253281Z,2020-05-19T13:08:20Z,-56,667G,rssi,wifi_status,ESP32
|
|
||||||
```
|
|
||||||
|
|
||||||
Accessing data using `FluxQueryResult` requires knowing the query result structure, especially the name and the type of the column. The best practice is to tune the query
|
|
||||||
in the `InfluxDB Data Explorer` and use the final query with this library.
|
|
||||||
|
|
||||||
Browsing thought the result set is done by repeatedly calling the `next()` method, until it returns false. Unsuccessful reading is distinguished by a non empty value from the `getError()` method.
|
|
||||||
As a flux query result can contain several tables, differing by grouping key, use the `hasTableChanged()` method to determine when there is a new table.
|
|
||||||
Single values are returned using the `getValueByIndex()` or `getValueByName()` methods.
|
|
||||||
All row values at once are retrieved by the `getValues()` method.
|
|
||||||
Always call the `close()` method at the of reading.
|
|
||||||
|
|
||||||
A value in the flux query result column, retrieved by the `getValueByIndex()` or `getValueByName()` methods, is represented by the `FluxValue` object.
|
|
||||||
It provides getter methods for supported flux types:
|
|
||||||
|
|
||||||
| Flux type | Getter | C type |
|
|
||||||
| ----- | ------ | --- |
|
|
||||||
| long | getLong() | long |
|
|
||||||
| unsignedLong | getUnsignedLong() | unsigned long |
|
|
||||||
| dateTime:RFC3339, dateTime:RFC3339Nano | getDateTime() | [FluxDateTime](src/query/FluxTypes.h#L100) |
|
|
||||||
| bool | getBool() | bool |
|
|
||||||
| double | bool | double |
|
|
||||||
| string, base64binary, duration | getString() | String |
|
|
||||||
|
|
||||||
Calling improper type getter will result in a zero (empty) value.
|
|
||||||
|
|
||||||
Check for null (missing) value using the `isNull()` method.
|
|
||||||
|
|
||||||
Use the `getRawValue()` method for getting the original string form.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// Construct a Flux query
|
|
||||||
// Query will find RSSI for last 24 hours for each connected WiFi network with this device computed by given selector function
|
|
||||||
String query = "from(bucket: \"my-bucket\") |> range(start: -24h) |> filter(fn: (r) => r._measurement == \"wifi_status\" and r._field == \"rssi\"";
|
|
||||||
query += "and r.device == \"ESP32\")";
|
|
||||||
query += "|> max()";
|
|
||||||
|
|
||||||
// Send query to the server and get result
|
|
||||||
FluxQueryResult result = client.query(query);
|
|
||||||
|
|
||||||
// Iterate over rows. Even there is just one row, next() must be called at least once.
|
|
||||||
while (result.next()) {
|
|
||||||
// Get typed value for flux result column 'SSID'
|
|
||||||
String ssid = result.getValueByName("SSID").getString();
|
|
||||||
Serial.print("SSID '");
|
|
||||||
Serial.print(ssid);
|
|
||||||
|
|
||||||
Serial.print("' with RSSI ");
|
|
||||||
|
|
||||||
// Get converted value for flux result column '_value' where there is RSSI value
|
|
||||||
long value = result.getValueByName("_value").getLong();
|
|
||||||
Serial.print(value);
|
|
||||||
|
|
||||||
// Format date-time for printing
|
|
||||||
// Format string according to http://www.cplusplus.com/reference/ctime/strftime/
|
|
||||||
String timeStr = time.format("%F %T");
|
|
||||||
|
|
||||||
Serial.print(" at ");
|
|
||||||
Serial.print(timeStr);
|
|
||||||
|
|
||||||
Serial.println();
|
|
||||||
}
|
|
||||||
|
|
||||||
// Check if there was an error
|
|
||||||
if(result.getError() != "") {
|
|
||||||
Serial.print("Query result error: ");
|
|
||||||
Serial.println(result.getError());
|
|
||||||
}
|
|
||||||
```
|
|
||||||

### Parametrized Queries
|
|
||||||
InfluxDB Cloud supports [Parameterized Queries](https://docs.influxdata.com/influxdb/cloud/query-data/parameterized-queries/)
|
|
||||||
that let you dynamically change values in a query using the InfluxDB API. Parameterized queries make Flux queries more
|
|
||||||
reusable and can also be used to help prevent injection attacks.
|
|
||||||
|
|
||||||
InfluxDB Cloud inserts the params object into the Flux query as a Flux record named `params`. Use dot or bracket
|
|
||||||
notation to access parameters in the `params` record in your Flux query. Parameterized Flux queries support only `int`
|
|
||||||
, `float`, and `string` data types. To convert the supported data types into
|
|
||||||
other [Flux basic data types, use Flux type conversion functions](https://docs.influxdata.com/influxdb/cloud/query-data/parameterized-queries/#supported-parameter-data-types).
|
|
||||||
|
|
||||||
Parameterized query example:
|
|
||||||
> :warning: Parameterized Queries are supported only in InfluxDB Cloud. There is no support in InfluxDB OSS currently.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// Prepare query parameters
|
|
||||||
QueryParams params;
|
|
||||||
params.add("bucket", INFLUXDB_BUCKET);
|
|
||||||
params.add("since", "-5m");
|
|
||||||
params.add("device", DEVICE);
|
|
||||||
params.add("rssiThreshold", -50);
|
|
||||||
|
|
||||||
// Construct a Flux query using parameters
|
|
||||||
// Parameters are accessed via the 'params' Flux object
|
|
||||||
// Flux only supports only string, float and int as parameters. Duration can be converted from string.
|
|
||||||
// Query will find RSSI less than defined threshold
|
|
||||||
String query = "from(bucket: params.bucket) |> range(start: duration(v: params.since)) \
|
|
||||||
|> filter(fn: (r) => r._measurement == \"wifi_status\") \
|
|
||||||
|> filter(fn: (r) => r._field == \"rssi\") \
|
|

## Original API
|
|
||||||
|
|
||||||
### Initialization
|
|
||||||
```cpp
|
|
||||||
#define INFLUXDB_HOST "192.168.0.32"
|
|
||||||
#define INFLUXDB_PORT 1337
|
|
||||||
#define INFLUXDB_DATABASE "test"
|
|
||||||
//if used with authentication
|
|
||||||
#define INFLUXDB_USER "user"
|
|
||||||
#define INFLUXDB_PASS "password"
|
|
||||||
|
|
||||||
// connect to WiFi
|
|
||||||
|
|
||||||
Influxdb influx(INFLUXDB_HOST); // port defaults to 8086
|
|
||||||
// or to use a custom port
|
|
||||||
Influxdb influx(INFLUXDB_HOST, INFLUXDB_PORT);
|
|
||||||
|
|
||||||
// set the target database
|
|
||||||
influx.setDb(INFLUXDB_DATABASE);
|
|
||||||
// or use a db with auth
|
|
||||||
influx.setDbAuth(INFLUXDB_DATABASE, INFLUXDB_USER, INFLUXDB_PASS) // with authentication
|
|
||||||
|
|
||||||
// To use the v2.0 InfluxDB
|
|
||||||
influx.setVersion(2);
|
|
||||||
influx.setOrg("myOrganization");
|
|
||||||
influx.setBucket("myBucket");
|
|
||||||
influx.setToken("myToken");
|
|
||||||
influx.setPort(8086);
|
|
||||||
```
|
|
||||||
|
|
||||||
### Sending a single measurement
|
|
||||||
**Using an InfluxData object:**
|
|
||||||
```cpp
|
|
||||||
// create a measurement object
|
|
||||||
InfluxData measurement ("temperature");
|
|
||||||
measurement.addTag("device", d2);
|
|
||||||
measurement.addTag("sensor", "dht11");
|
|
||||||
measurement.addValue("value", 24.0);
|
|
||||||
|
|
||||||
// write it into db
|
|
||||||
influx.write(measurement);
|
|
||||||
```
|
|
||||||
|
|
||||||
**Using raw-data**
|
|
||||||
```cpp
|
|
||||||
influx.write("temperature,device=d2,sensor=dht11 value=24.0")
|
|
||||||
```
|
|
||||||
|
|
||||||
### Write multiple data points at once
|
|
||||||
Batching measurements and send them with a single request will result in a much higher performance.
|
|
||||||
```cpp
|
|
||||||
|
|
||||||
InfluxData measurement1 = readTemperature()
|
|
||||||
influx.prepare(measurement1)
|
|
||||||
|
|
||||||
InfluxData measurement2 = readLight()
|
|
||||||
influx.prepare(measurement2)
|
|
||||||
|
|
||||||
InfluxData measurement3 = readVoltage()
|
|
||||||
influx.prepare(measurement3)
|
|
||||||
|
|
||||||
// writes all prepared measurements with a single request into db.
|
|
||||||
boolean success = influx.write();
|
|
||||||
```
|
|
||||||
|
|
||||||
## Troubleshooting
|
|
||||||
All db methods return status. Value `false` means something went wrong. Call `getLastErrorMessage()` to get the error message.
|
|
||||||
|
|
||||||
When error message doesn't help to explain the bad behavior, go to the library sources and in the file `src/util/debug.h` uncomment line 33:
|
|
||||||
```cpp
|
|
||||||
// Uncomment bellow in case of a problem and rebuild sketch
|
|
||||||
#define INFLUXDB_CLIENT_DEBUG_ENABLE
|
|
||||||
```
|
|
||||||
Then upload your sketch again and see the debug output in the Serial Monitor.
|
|
||||||
|
|
||||||
If you couldn't solve a problem by yourself, please, post an issue including the debug output.
