DS18B20温度读取，DS1820 数字温度计提供9 位温度读数,指示器件的温度

信息经过单线接口送入DS1820 或从DS1820 送出因此从中央处理器到DS1820 仅需连接一条

线和地读写和完成温度变换所需的电源可以由数据线本身提供而不需要外部电源

因为每一个DS1820 有唯一的系列号silicon-DS18B20 temperature read, DS1820 digital thermometer for temperature readings 9, instructions device temperature information through a single interface into DS1820 or DS1820 therefore sent from the central processing All of the DS1820 just connected to a line and read and write and complete the transformation temperature of the power supply can provide data line itself without the need for external power supply because each one DS1820 is the only series of silicon
