Temperature control is quite extensive in their daily lives and industrial applications, and past temperature control is done by hand and not enough attention, in fact, temperature needs to be monitored in many places in order to prevent accidents. To solve this problem, a temperature control system based on 51 Single Chip Microcomputer (SCM) is designed in the paper. Combining with SCM AT89C51, temperature sensor is used to collect temperature, the collected temperature values are transferred to the LED display to shows. Then cooling or heating is automatically operated by the fan or an electric wire in order to achieve a constant temperature. The experimental results show that the system can perform real-time monitoring of temperature and reach the goal of effectively controlling temperature.
