Design of Temperature Measurement System Based on Microcontroller

Abstract:

This temperature measurement system is based on the control of AT89S52 single chip microcontroller, with temperature display function. Temperature information is changed into digital signal directly by a single bus digital temperature sensor DS18B20, and the digital signal is sent into microcontroller for real-time acquisition. The results are displayed through LCD module 1602 in real time. The system is with the characteristics of low cost, high precision, stable performance and convenient operation. The system can be extended to multi-point temperature detecting system easily, and adding temperature transfinite alarm function.
