At present, in most users’ families, the light control is still switched on and off by pressing keys. When users forget to turn off the lights when going out, the lighting system in the home will be powered on and lead to a waste of electric energy. Therefore, an intelligent light control is designed. The system simulates the lights in three rooms (living room, bedroom, bathroom) through three LED lights; The three lights can be turned on and off through three buttons; The human body pyroelectric detection is used to detect whether there is a person at present, and the lighting intensity is less than the set minimum value to control the lighting on, which can be automatically adjusted according to the current lighting intensity. Through this design, when it is detected that there is no person in the room or the light intensity is greater than the set maximum value, the lamp will not light up, which can save a lot of resources.
