Design And Implementation Of A Microcontroller-based Temperature Control System

Traditional thermometer has many shortcomings, just as single performance, short lifeexpectancy, poor reliability and low accuracy. The emergence of digital thermometer solvedall of these problems; it not only widened the application area of the thermometer, but has anadvantage of real time, accuracy and efficiency.A practical temperature measuring method based on microcontroller, Pt100resistanceand ADS7816analog-to-digital converter was presented in this article.It includes the overall design method, the particular design of hardware circuit and thesoftware implementation. The temperature measurement range between0and100degreecentigrade, the measurement accuracy is0.1degree centigrade.Respectively, using the PID algorithm and a fuzzy control algorithm to control thetemperature in the temperature control module...
