/**
* 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
