Design of Temperature Monitoring Node Based on Wireless Sensor Network

A design scheme of temperature monitoring node of real-time temperature monitoring system for high-voltage electrical equipments based on wireless sensor network was introduced. The node is consisted of microprocessor MSP430F2012, temperature sensor DS18B20 and wireless transceiver controller nRF24L01. In process of temperature monitoring, the temperature sensor collects temperature data regularly and sends the data to the microprocessor for processing, then the node sends real-time temperature data to base station through the wireless transceiver controller. The node achieves real-time monitoring of high-voltage electrical equipment, satisfies the demand on low power consumption, and improves stability of the equipments and reliability of the monitoring system.
