摘　　要：DS1820温度传感器是一种单总线型温度测量器件,具有直接的数字信号,可采用总线供电,在同一根总线上可接多个传感器,构成多点测温网络,是温度场监控系统的理想选择。DS18B2单总线工作方式和无需内部单独供电的寄生电源供电工作方式,解决了传统的测温系统硬件结构复杂、测温系统中的引线误差补偿问题。The DS18B20 temperature sensor uses the＇one wire＇protocol with the direct digital signal and its electricity supplied by the one cable, as well as there are many sensors connected so that a many measurements temperature network is formed. The DS18B20 operation model of requiring no sneak power supply provides a solution to the problems of the over-complexity and the lead wier errors＂ offset of temperature sensor hardwares .
