LoRa Based Switch Control with Arduino

In this project, a LoRa Relay Switch or LoRa Based Power Relay Control System using Arduino & RFM98 LoRa Module. The LoRa Relay Node will able able to transmit the data to Gateway.

We can press the switch button on Sender or LoRa Node side which can turn OFF/ON the relay remotely.

The LoRa Relay Power Switch is a smart LoRa device for remotely controlling industrial and home appliances remotely.

The Remote Power Switch can be used to remotely control the power of external devices or appliances.

Appliances include the control of general devices, lighting, irrigation systems, pumps, remote servers, towers, enabling and disabling security systems, access control of gates and doors.
Communication with the Remote Power Switch is done using the integrated loRaWAN module.

All you need to do is upload the code using Micro-USB port, connect to your LoRaWAN network, connect the Remote Power Switch to your power outlet, and connect your appliances to the Remote Power Switch.

LoRa uses license-free sub-gigahertz radio frequency bands to enable efficient long-range transmissions of more than 10 km with extremely high wireless link budgets of around 155 dB to 170 dB.
