1. automatic induction: when someone enters its sensing range input high, people leave the sensor range automatic delay off high. Output low.
2. photosensitive control (optional): module is reserved for the location, you can set the photosensitive control, daytime or light sensing. The photosensitive Control optional features not installed at the factory photoresistor. If necessary, please purchase separately photoresistor install it yourself.
3. two trigger modes: L can not be repeated, H can be repeated. Jumper selectable, default is H.
4. induced blockade time (default setting: 0.2 seconds): sensing module in every sensor output (high to low) followed by set up a blockade of the time, in this period of time the sensor is not receiving any induction signal. This feature can be achieved both of the (inductive output time and the blocking time) interval can be applied to the interval detection products; This feature can effectively suppress the various interference generated in the process of load switching.
5. micro-power: quiescent current of 65 microamps, particularly suitable for battery-powered electrical products.
6. output high signal: easy to achieve docking with the various types of circuits.



Pyroelectric infrared switch is a passive infrared switches BISS0001 accompanied pyroelectric infrared sensor and a small amount of external components. Can automatically and quickly turned on all types of incandescent lamps, fluorescent lamps, buzzer, automatic doors, electric fans, dryer and automatic washing machines and other devices, is a kind of high-tech products. Especially suitable for enterprises, hotels, shopping malls, warehouses and family aisles, corridors and other sensitive areas, or for the security zone, automatic lighting, lighting and alarm systems.





Pyroelectric infrared sensor is capable of detecting human or animal infrared emission and output signals of the sensor. In early 1938, people put forward using pyroelectric infrared radiation, but did not get attention, until the sixty's, with the development of laser, infrared technology is developing rapidly, it also promoted the study on the pyroelectric effect and application of pyroelectric crystal. Pyroelectric crystal has been widely used in infrared spectrometer, infrared remote sensing and thermal radiation detector, it can be used as an infrared laser of an ideal detector. It iswidely applied to various automatic control device. Besides the well known in our corridor automatic switch, anti-theft alarm has been applied in more and more fields, application prospects. For example: no one in the room will automatically shut down the air conditioner, water dispenser.Television can judge unmanned watch or the viewer has to sleep after the automatic shutdown mechanism. Turn on the monitor or the application of automatic door. Combined with the camera or digital camera automatically record the animal or human activities ... .... You can according to their own ideas, combined with the other circuit developed new products more outstanding. Or automation control device.
