-Laura utilises [[:interfaces:semtech|LoRa]] radios with at least one transmitter on an ATMega or STM32 acting as a sensor and the other as a receiver on a Raspberry Pi running as a processor of the sensor readings.

The software has been written to support the 868 MHz EU band only.
  
 This project was designed to monitor the humidity of a remote location and as such has been written to support (initially) one of three humidity sensors boards, namely the DHT11, [[:interfaces:aht10|AHT10]] and SHT3X. This project was designed to monitor the humidity of a remote location and as such has been written to support (initially) one of three humidity sensors boards, namely the DHT11, [[:interfaces:aht10|AHT10]] and SHT3X.
