DS18S20：1-Wire寄生供电数字温度计
DS18S20数字温度计提供9位摄氏温度测量，具有非易失性、上下触发门限用户可编程的报警功能。DS18S20通过1-Wire®总线与中央微处理器通信，仅需要单根数据线(和地线)。DS18S20具有-55°C至+125°C的工作温度范围，在-10°C至+85°C温度范围内精度为±0.5°C。另外，DS18S20能够直接由数据线获取电源(“寄生电源”)，无需外部工作电源。 每片DS18S20具有唯一的64位序列码，这些码允许多片DS18S20在同一条1-Wire总线上工作，因而，可方便地使用单个微处理器控制分布在大范围内的多片DS18S20器件。从中受益的应用包括：HVAC环境控制、室内，设备或者机器内部的温度监测系统、过程监控和控制系统。
