Passive Infrared Arrays | PIR - Fresnel Tech

Fresnel lens arrays for passive infrared (PIR) applications are useful in a wide range of devices, such as automatic lighting switches, occupancy sensors, and motion sensor alarms. Fresnel lens arrays for PIR applications produce a broad, tailored field of view through the accumulation of many repeated narrow fields of view.

detection - Sample Application with LHI 778 PIR Sensor ...

At first I also wanted to remark that you need a lens with the PIR sensor, but that may not be so. The sensor has a wide viewing angle and won't detect motion once the person is in its view. Russell talks about a Fresnel lens to remedy this. A Fresnel lens is just a common lens which is flattened in a way that retains the lens' curvature.

Lens and Focusing Devices for Pyroelectric Infrared Sensors

The groove side of the lens usually faces the PIR sensor. A Fresnel lens both captures more IR radiation and focuses it to a small point. This focal point moves across the sensor as the IR source moves and exposes one element at a time. A Fresnel lens can extend detection range to about 100 feet. A Fresnel lens will give the best possible ...

Passive infrared sensor - Wikipedia

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved.

Enhanced-Range Intrusion Detection Using Pyroelectric ...

As the intruder passes in front of the PIR sensor, a Fresnel lens modulates the incident heat flux by partitioning the FOV into multiple segments1 as shown in Fig. 2(a), where each seg-ment concentrates the flux onto the PIR sensor. Consequently, the PIR sensor’s signal depends on the intruder’s trajectory through the FOVs.
