摘要
针对采用热敏电阻测温和有线温度测量系统的不足,提出了采用单总线数字温度传感器DS18B20、单片机和无线收发模块等组成智能无线温度监测系统。DS18B20具有体积小,精度高,采用一线总线,可组网等优点,短距离无线通信技术应用到多点温度测量中,实现了温度数据无线传输,该系统扩展维护方便、成本低、高可靠性等特点,具有一定的实用性。
Aiming at that the temperature measurement system usually used thermal resistance and disadvantages of system with cable wiring,a smart wireless temperature measurement system is proposed,which is composed of 1-wire digital temperature sensor DS18B20,single-chip microcomputer and wireless transmission module.DS18B20 has smaller size,higher precision,1-wire bus and the advantages of networking.The wireless communication technology is applied to the temperature measurement system with multi-point,and its temperature data is transmitted.This system has advantages of low cost,high reliability and strong practicability.
