Only compatible with ESP32

IMPORTANT : to make it work, you will need the help of an additionnal ADC converter because the one on the ESP32 isn't accurate enough. Here we used an ADS1115 from Adafruit

You can find it here : https://www.adafruit.com/product/1085

And here is the library you'll need to add to your sketch : https://github.com/GreenPonik/Adafruit_ADS1X15
