However it will pass through, with some attenuation, material that is opaque to visible light such as germanium and silicon. The Panasonic PIR Motion sensors abbreviated as PaPIRs, has three series of pr oducts, including - EKMB(WL) with low current consumption - EKMC(VZ) for general use - AMN(NaPiOn), the traditional type. These slots are made of a special material which is sensitive to IR. DPP25 has a lower met flow rate than DPE200, so it takes more time to inject Fresnel … So, pretty much any plastic optical component will be made out of acrylic (lenses, some sheet plastic) or polycarbonate … When a human body or any animal passes by, then it intercepts the first slot of the PIR sensor. Fresnel uses optical-quality materials for lens and lens array design. 5111.

Often PIR optics is composed of numerous Fresnel lenses made of high-density polyethylene (DPE) plastics having the refraction index of 1.54 [4]. There is another problem: A PIR lens consists of a bunch of fresnel lenses. Is it possible to replace this PIR lens, or do I have to throw the baby out with the bathwater and replace the whole sensor piece? The best manufacturing practices and materials are everything. Design. Today I introduce POLY material DPP25 and DPE200 for PIR Fresnel Lens. Lastly, for any PIR sensor, it is necessary to use a lens in front of the sensor to extend the detection range by focusing the infrared energy onto the sensor elements. So as you move across the field, the heat it picks up goes in and out of view. The Plane PIR Fresnel lens is primarily used to transmit infrared light. In Stock: 875. #7 Feb 20, 2016, 10:34 pm. Seems to be working fine in my other camera. Fresnel lens: According to the Fresnel principle, the Fresnel lens is divided into two types: refractive and reflective. The PIR lens/translucent cover for my motion sensor for my outdoor light kit broke. Obviously, DPE200 has cheaper price and higher transmittance rate than DPP25. The groove side of the lens usually faces the PIR sensor.

When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. PIR is an electronic sensor which detects the changes in the infrared light across certain distance and gives out an electrical signal at its output in response to a detected IR signal. A Fresnel lens is usually thin and flexible and is about 0.015 inch (0.38mm) thick with grooves molded into one surface. A Fresnel lens both captures more IR radiation and focuses it to a small point. For quality optics germanium is a common material for PIR lenses and not cheap. Categories » PIR Fresnel Lens.
