With the development of modern industry, people's living standards are improving, and has created enormous wealth for human society. The key of the development level of modern industry is how to measurement and control the various parameters among the industrial control accuratly, and current, voltage, temperature, pressure, flow, flow rate and switching capacity all are commonly used parameters which are mainly controlled. Among them, the temperature measurement is the key technologies in the industrial production .
The design designed a new temperature control system by using of STC12C5410 and temperature sensor DS18B20.The temperature is showed on the LCD1602 by the MCU. Temperature measurement and control can be used in various fields, such as people's lives, automotive services, industrial production superior. Therefore, the temperature control system has good prospects for development.
