Many people dream of having a good sleeping environment indoor. In this paper, combining with the sleep medicine knowledge and automatic control theory, we propose a sleep environment intelligent control system design scheme, which uses the single chip processor as the controlling core and integrates various household electrical appliances. In this design, we will introduce the overall plan of the system, the control strategy, software design and implementation. The actual test shows that practical value of the system is high, it not only can effectively improve sleep environment also can help the research related to the sleep medicine.
