Hardware

Microcontroller

The firmware has been developed and tested on a LILYGO T3 V2.1.6 LoRa32 microcontroller. Other boards can be targetted and I've successfully tested it with the Heltec WiFi LoRa 32(v2).

Sensors

The firmware recognises sensors connected to the I2C bus.

LoRa

The device communicates through any LoRaWAN gateway that is in range. This firmware has been tested using a Laird Sentrius RG186.
