Digital thermometer uses the integrated chip to overcome the above problems. Its major features are small volume, and conveniently portable.According to the different temperature acquisition device, more specifications thermometer ofthe different accuracy or temperature measurement range is produced.This paper introduces a portable digital thermometer, with P89V51RD2 as the main controller, sensor DS18B20 as a temperature acquisition chip, ampire128x64 LCD screen to display.Using Proteus simulation circuit diagram, Keil design program coding, alignment simulation results are obtained.Measurement of the temperature range of the system is -10 ～ 100 ℃, the temperature value is accurate to 1 decimal places. This system has...
