Research and Implementation of Temperature Control System Based on Single Chip Microcomputer

Temperature measurement and control is an important link of many industrial production activities. The single- chip temperature control system are introduced; temperature data are acquired using digital temperature sensor,which are transmitted to the AT89S51 microcontroller. Pre- set temperature in the system,and based on the detected temperature data decide whether or not to employ cold junction compensation method in the process of using thermocouple sensor,so as to realize efficient temperature control.
