One of the first sensors being tested is built using a Teensy LC Arduino compatible module and a HopeRF RFM92W LoRa transceiver module. This is currently made up on a temporary breadboard to determine if this actually works correctly and what the range of the RFM92W module is. Further developments are using the MultiTech Systems mDot module.
