Aiming at problem that electrical equipment monitoring communication mode has defects of short transmission distance and complex network

a design scheme of temperature and humidity monitoring terminal for electrical equipment based on LoRa is proposed.An enterprise architecture of temperature and humidity monitoring system for electrical equipment based on LoRa is presented. LoRa sensing terminal in the system is designed

communication test under the laboratory environment is carried out. Low power consumption design and test are carried out.Test result shows that the designed terminal equipment is especially suitable for battery power for its sleep current is 1. 4 μA and the average operating current is 0. 070 mA. The system has the advantages of long transmission distance and low power consumption.
