4-Channel LoRa Relay Kit with Controller(868M)
This Lora control relay kit includes a 4-channel Lora relay and a remote controller.
It is the ideal solution for remotely controlling loads over considerable distances (a few km as the crow flies).
This Kit allows you to activate remote loads and create a complete remote control system with feedback. This LoRa relay and controller are Aurel half-duplex radio transceiver in which the Semtech LoRa modulation technique is implemented, which ensures long-distance communications, high immunity to interference, high sensitivity and low consumption in relation to the distances covered.
Compares to ordinary RF433/868 remote control, this LoRa kit features:
- Much longer control distance, from hundreds of meters to KM;
- Loop-control, the controller sent Lora commands to relay, and then get relay feedback, to create safe ensured controlling.
- Hardware Open source for free remaking;
- Firmware based on Arduino, open source, for users free to change/alter/upgrade, for example, change the “Output Power” higher, such as 13, for even longer control distance (but more power cost)
Note The relay and controller need a simple pairing step before common usage:
