Electronic Thermometer Design Based on Pt100
Huibin Qin · 2005
The fundamental constitute and working elements of electronic thermometer was elaborated. Making use of the temperature and resistance characteristic of the Pt100, temperature signal was converted to electric signal firstly. Then the electric signal was transformed to digital signal and displayed in LCD with control program of MCU. The electronic thermometer can detect temperature from -40℃ to 120℃.
