To improve the property and simplify the structure of temperature control system , the intelligent temperature control system based on PID algorithm is designed , which achieves real-time temperature measurement , closed-loop control and real-time display by high-performance C8051F series of MCU . It not only simplifies the hardware structure , but also enables designers to reuse and expand , because each module is independent from each other , which enhances the anti-interference and reliability as well . Experiment results show that its temperature response time is 3 s~5 s , temperature control error is 1%, which makes it valu-able in thermostatically controlled occasions .
