By using the digital voltage meter module,constant current source,AD620,we designed the temper-ature measurement circuit. And we made 0~100℃ digital thermometer. It had a high linearity,fast heat re-sponse speed,high accuracy,light weight,easy manufacture,and low cost advantages. The digital thermometer can be measured in solid,liquid and gas temperature,which has a wide range of uses.
