Design of Temperature Monitoring System Based on Wireless work
Abstract
Temperature and humidity are closely related with the daily production and life, and in many circumstances we need to collect and monitor the temperature. This paper tries to design a temperature monitoring system, including system identification program, the module hardware and soft- ware design, basing on the theory of wireless works and knowledge of microcontroller, integrated sensors, wireless transceivers. This system can achieve real-time temperature testing, and can send temperature information to end-users to realize the dynamic monitoring of the terminal monitoring interface through the wireless transceiver. End users can also send control information through wireless transceiver to control the temperature. To a certain extent, this system can achieve automatic control and e the distance problem, having a broad application prospect
