Design and realization of a intelligent mixed water valve control system

In our daily life, constant temperature water is needed everywhere. When we are bathing, it is inconvenient to control the water by hands and the temperature of the water overflowing is changing all the time. In order to control the temperature to be constant, this paper proposed a valve controller intelligently controlled by microcontroller. Consumers can set the temperature they want and the sensibility and stability of the intelligent controller is met perfectly. In this paper we displayed how to design the controller by the hardware and the software. Moreover, we give the debug result and prospect the future of our novelty controller. Our research and design will promote development of intelligent household application.
