Abstract
The temperature is attributes the object cooling degree the physical quantity, is also one kind of most basic environment parameter. In the agriculture industrial production and the daily life, is occupying the extremely important status throughout to the temperature survey and the control.
At present, as representative's new single main line digital temperature sensor collection temperature survey and A/D transforms take DS18B20 in a body, the direct output digit quantity, is simple with the monolithic integrated circuit interface circuit structure, the widespread use in is away from, the node to distribute many situations far, has the strong promotion application value.Use monolithic machine to monitor the temperature height, DS18B20 has used the acquisition real time temperature.
