F11 Square Fresnel Lens for SMD PIR Motion Sensor is specially designed for the SMD type PIR sensor, which is widely used in the smart home, smart device, lighting, and alarm. Because of its  Because of its mini size, it is also preferred by many customers to work with normal DIP PIR sensors.

The Fresnel lens is an optical component, 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.
