Human emission of infrared after Finel filter enhanced gathered using pyroelectric component made of the infrared inductive source, loss of charge balance in the human body induction head receives the infrared radiation temperature changes, outward release charge, following circuit IC IC test after treatment can generate alarm signal. And with the photosensitive element to control the circuit working environment, in the light intensity is very weak environment, in the distance inductive switch 4-5m place, there is the human body after the induction the source receives the infrared signal transmitting circuit is switched on the human body, and light lighting appliances, human again after the action of an infrared transmitting, then up again. Results show that satisfy the illumination conditions in the light, the switch can be convenient to start and stop, the fly in the ointment is that inductive head after occlusion cant work properly. Application of a human body induction switch, has a lot of significance for convenient environment protection of life, can be applied to many public or home
