Especially the variety of intelligent instruments, meters in the agricultural, industrial society to the broad application brought great convenience. In this paper the characteristics of the model and temperature control, the introduction of SCM PIC16F877 at the core, with AD7416 digital temperature sensor to measure the temperature. PID algorithm to control the temperature , and temperature control for good accuracy. Many parts of the system such as, timers, heating switches, buttons installed water temperature, real-time display of temperature, temperature control and alarm functions, such as insulation SCM can be used to achieve. The article highlights the core device of choice, temperature control system, part of the circuit and software design. It has a simple structure, reliability, and strong interference capability to achieve easy, low cost, has practical value, and other characteristics. It provides a temperature controlled equipment through the basic ideas and principles, I believe in the practical application of our life more convenient.
