This code implements a circuit system based on 51 SCM, which is used to control the temperature of the water in heater by a SCM. The system is composed of three sections: the module of measuring temperature system, the module of controlling temperature system and the module of software. The digital thermometer gives the temperature value of the water to the SCM, which display the current temperature even and again. Through the comparison of the target temperature and the current temperature, the SCM export a control signal to control the heater s condition (on/off) by relay, to realize the function of controlling the temperature and keeping the temperature.
