1DS18B20简介DS18B20数字温度计提供12位[二进制]温度读数,指示器件的温度。信息经过单线接口送入DS18B20或从DS18B20送出,因此从主机CPU到DS18B20仅需一条线[和地线],每一个DS18B20在出厂时已经给定了唯一的序号,因此任意多个DS18B20可以存放在同一条单线总线上。-DS18B20 brief introduction 1DS18B20 digital thermometer to provide 12-bit [binary] temperature readings, the temperature of the device instructions. Information through one-way interface into DS18B20 or from DS18B20 sent from the host CPU to DS18B20 only one line [and ground], each DS18B20 at the factory has given a unique serial number, it can be any number of DS18B20 stored in the same one-way bus.
