LoRaWAN Smart Electricity Safety Monitor
Description
The EFM-02 Smart Electricity Safety Monitor is an intelligent monitoring device based on LoRaWAN technology, specifically designed for remote surveillance of electrical circuits. Capable of real-time monitoring and recording of critical safety parameters of the electrical circuit, such as residual current, temperature, power,current intensity, and voltage, the device uploads this data to a cloud platform. Utilizing advanced data analysis techniques, the cloud platform performs a comprehensive diagnosis of potential electrical safety hazards and issues timely alerts for conditions like electrical leakage, overload, or short circuits. This effectively prevents electrical fires and ensures the safety of electrical usage.
