WLC-NEMA-03 interface single lamp controller

The electrical fire monitor can collect the voltage values of the monitored equipment and upload them to the cloud platform through LoRa. The cloud platform can determine the operating status of the monitored power supply, such as voltage, current, residual current, and temperature. By accumulating and deeply mining data, from "describing alarms" to "diagnosing causes", an effective warning mechanism is established to nip electrical hazards in the bud before they occur.
