Monitor sensors and control devices over long distances using LoRa technology. For this project, we perform bi-directional communication, enabling both units to have the ability to transmit and receive data.
This project allows us to monitor two sensors on a sensor unit and have their on or off state displayed on a base unit, which can be located up to many kilometres away. We can then send a signal back to the sensor unit to trigger a relay, which, in turn, operates a connected device.
