Research and implementation of temperature Control system based on single Chip Microcomputer

In this paper, a temperature control system based on STC8952 single chip microcomputer is designed, which can store relevant temperature data in real time and record the current time. The system can be used as the core of the system control, and the object SET-300 temperature measurement and control instrument provided by the laboratory is acquired through the DS1820 temperature sensor. The system can output the PWM wave form according to the PID algorithm, output the PWM waveform, turn on and turn off the heating power supply automatically according to the PID algorithm, so that the temperature value in the control instrument can be stabilized within the set range.
