Aiming at the hidden trouble that the surrounding and internal temperature of substation switchgear, main transformer, capacitor terminal box and other equipment is too high and should not be detected, a wireless temperature and humidity sensor that can work stably in high electromagnetic field, large current and high temperature for a long time has been developed.

The product adopts ultra-low power consumption design, radio frequency communication, CRC calibration and other technologies. It is green, maintenance free, completely isolated, easy to install, strong anti-interference ability, reliable operation, compact size and other characteristics, which can well solve the temperature and humidity measurement problem under high voltage state. The collected temperature and humidity are transmitted to the monitoring terminal through RF communication in real time to achieve uninterrupted and accurate measurement.

This product uses the 2.4GHz LoRa wireless communication technology platform, and the communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid power transmission and transformation equipment to achieve dual-way communication, realize intelligent management of the operating temperature of power equipment, and provide data support for the safe operation of power grid equipment. Application field: online monitoring of temperature and humidity of various switch cabinets, main transformers, capacitor terminal boxes, etc.
