Temperature Control of Refrigerator Based on Single Chip Microcomputer
Abstract  This paper mainly discusses the hardware circuit and software design for temperature control of thermostat. The purpose of temperature control is achieved by testing the Proteus simulation physical diagram. AT89C51 single-chip computer is selected as the hardware core, and independent design is adopted, which includes temperature monitoring, compressor cooling, display module and so on. Through comparing the actual temperature and the set temperature in the box, the cooling and heating control is carried out, accompanied by LED status display. When the temperature is higher than the set upper limit, the buzzer alarms. The thermostat completed by this design mainly realizes heating and cooling control, and meets the application requirements in life.
