LG-01 based on LoRaWAN standard protocol has the characteristics of long transmission distance, low power consumption, product stability, high detection accuracy, and has the advantages of no wiring, simple installation, and low cost. All LoRaWAN protocol nodes can collect the information collected in the field to the LoRaWAN gateway.The gateway converts it into Modbus/BACnet protocol commonly used in building control or MQTT protocol of the Internet of Things to solve the problem that the traditional building control design can not take into account the distance, anti-interference and power consumption.
