|
* Basic Write Example code for InfluxDBClient library for Arduino
|
|
* Data can be immediately seen in a InfluxDB UI: wifi_status measurement
|
|
* Enter WiFi and InfluxDB parameters below
|
|
*
|
|
* Measures signal level of the actually connected WiFi network
|
|
* This example supports only InfluxDB running from unsecure (http://...)
|
|
* For secure (https://...) or Influx Cloud 2 use SecureWrite example
