This Fresnel Lens is widely used in human motion switch, intrusion alarm system, infrared thermal sensor. There are different angles, detect distance, size for you choose. This is the most popular item in the market. The Fresnel lens is an optical element, one side is smooth, another side is by a ring a part of concentric garden composition.
Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for the PIR sensor application. All the PIR sensor must work with the Fresnel Lens. Fresnel lens is more competitive than the traditional optical lens.
Note: It does not includes BM612 PIR sensor.
