High Precision 1-Wire Digital Thermometer

DESCRIPTION The DS18S20 Digital Thermometer provides 9–bit temperature readings which indicate the temperature of the device. Information is sent to/from the DS18S20 over a 1–Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a 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。\n\n 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 • 独特的1-Wire®接口，通信只需要一个端口\n\n• 最大程度提高各种热管理应用的系统精度\n• 温度测量范围：-55°C至+125°C (-67°F至+257°F)\n\n• -10°C至+85°C温度范围内具有±0.5°C精度\n\n• 9位温度计分辨率\n\n• 无需外部元件\n\n\n\n\n• 寄生供电模式只需要2个引脚即可工作(DQ和GND)\n\n• 多节点共用同一总线，简化分布式温度检测\n• 每个器件具有唯一的、存储在片内ROM的64位序列码\n\n\n\n\n• 用户可定义的非易失性(NV)报警设置，报警搜索命令能够识别温度超出设定门限的器件\n\n• 8引脚SO (;
