摘要
阐述了数字温度传感器DS18B2 0的功能、结构、测温原理以及在多点温度测试系统中的应用 .由于其精度高、互换性好 ,可直接将温度数据进行编码 ,且可以只使用 1根电缆传输温度数据 ,通信方便 ,传输距离远且抗干扰 ;系统得以简化 ,扩充维护十分方便 .
The function ,structure and principle of temperature measurement of digital temperature sensor and its application in multiple temperature measurement system are introduced. With its high accuracy and good exchange capacity,this sensor can card temperature data directly ,and transmit information through 1-wire bus. So communication become more convenient and with high ability to resist interference.DS18B20 multiple temperature measurement system can save a lot of cables compared with the maltiple temperatare measarement system consisting of fradifional sensers.
