Automatic control system of temperature based on MCU Abstract Temperature control system can be said to be ubiquitous, water heaters, air conditioning systems, refrigerators, rice cookers, electric fans and other home appliances as well as high-speed and efficient hand-held computers and electronic equipment are required to provide temperature control. With the development of national economy and the people domestic industrial needs of various household appliances and industrial equipment temperature control by single chip microcomputer to control them not only has simple control, convenience and flexibility advantages and can greatly increase the temperature was charged with the technical indicators which can greatly enhance the quality and quantity. At present, the water temperature control system used by the analog temperature sensor analog transmission system switch A/D converter and microcontroller. Water temperature control method is used widely in industry classification more in daily life and different temperature control system are not the same. The system design can be used for drinking water heater temperature control systems and other electrical circuits. AT80C51 microcontroller as the core of it, through the three temperature digital display and 4 keys to achieve man-machine dialogue, the use of single-chip bus temperature conversion temperature DS18B20 real-time acquisition and through the digital display and offers a variety of operating light to indicate system now live in the state, such as: temperature setting, heating, and stop heating, the entire system through the four buttons to set the heating temperature and control the
