Abstract: Multi-point temperature monitoring of coal belt conveyor base on Zigbee technology is designed in the paper.The temperature was collected by DS18B20 bus digital temperature sensor with simple structure and flexible operation.The system uses the ultra-low power dormancy arousal model of microprocessor MSP430F436 to save power.The test results show that the system can measure and display the value of the temperature exactly,and further more it is highly real-time and reliable with small frame and low cost and low power.
