Optical Fresnel Lens D7002 For Smart Home System

Product Details

Overview

PIR sensor must work with the Fresnel lens, to insure the long detect rang. Fresnel lens is the precision optical lens. Combining the products case, we can design different shape for fresnel lens. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens. Fresnel Lens can be made of polyolefin, glasses. One side is smooth, another side with thread. The model number is d7002c.

Owning very strong R&D Center, Senba can research and develop the pyroelectric infrared sensor independently. Among those china sensor manufacturer, Senba Sensor has become the first owner of this special pir sensor technology enterprise in China. We are awarded as "Henan high-tech enterprises" in 2006 and awarded as "Notional high-tech enterprises" in 2012.

Digital Signal Processing Passive Infrared Sensor D202X

D202X is 2 elements PIR sensor, with small detection angle. Mainly used for toys and other small angle requirement products.

PIR sensor sense the motion object, always used to detet the human. There is a detect rang for the PIR sensor. When a people move in or out of the detect rang, the PIR sensor will be triggered. PIR sensor are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control. PIR sensor also named passive infrared, Pyroelectric or IR motion sensor.
