| Abstract: | 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. |
