The main body infrared sensor switch device for human pyroelectric infrared sensor. Pyroelectric infrared sensor body: the body has a constant body temperature, usually at 37 degrees, it will issue a specific wavelength of about 10UM infrared, passive infrared sensor to detect the human body is the infrared emission around 10UM carried out the work. 10UM launched around the body through infrared filter to enhance Philippine soil after Seoul gather infrared sensors source. Infrared sensors are usually used in pyroelectric element, this element in the received infrared radiation temperature changes will be lost when the charge balance, the release of sensitive infrared sensors outside the charge, the subsequent processing circuit can be triggered by the detection of switching. When someone enters the switch sensing range, special sensors detect the infrared spectra of the human body, the switch automatically switches the load, do not leave the sensor range, the switch will continue to turn; people left in the induction area or no action, the switch delay automatically turn off the load. People to the lights, people from the lights out, friendly convenience, safety and energy saving, but also show humane care, and because it is sensing the body heat control switch, so to avoid invalid electric power consumption,save energy. 关键词Pyroelectric infrared sensorInte
