pir lens material

high reliability and environment-friendly materials. High quality and best price PIR sensor fresnel lens Model 1/4 sphere Model 1/4 sphere Size Refer to drawing Material HDPE Focal length 30mm Angle 100° Distance 10m Spec list Sample showing Contact information Shenzhen Meiying Optics Co. Guangdong China Application 1.High quality ,Best service ,Superior after-sales service 2.Main Markets:European ,American ,Japanese and Korean etc. PIR Fresnel Lens … Get it as soon as Wed, Dec 16. Categories » PIR Sensor Lens Cover. I have tried an unpolished clear case and a polished clear lens (not polished well enough for a camera but works as a magnifying glass). Various lenses, digital and analog types are available: PIR Motion sensors (Passive Infrared or Pyroelectric) from Panasonic for optimal … PIR lenses require special materials to ensure the lowest possible signal loss. Our custom materials let more of the signal through! Using a Fresnel lens, the infrared image for the viewing area is spread across all of the sensor elements. Often PIR optics is composed of numerous Fresnel lenses made of high-density polyethylene (DPE) plastics having the refraction index of 1.54 [4]. I have emailed Moultrie numerous times, but have gotten no responce. 5111. The PIR lens/translucent cover for my motion sensor for my outdoor light kit broke. So sometimes your body heat is focused on the detector, sometimes it is not. So you cannot use a cover that is translucent to IR. the second function is divides into the search coverage in certain area pellucidae and the dark area, causes to enter the search coverage the motion object to be able to … Passive Infrared PIR Fresnel lens is made of milky white flexible, 0.4mm thick HDPE with UV protection. The lens shape and size, therefore, determines the overall detection angle and viewing area. IR Fresnel Lenses, Lenses for PIR Application, PIR Frensnel Lens manufacturer / supplier in China, offering Aspherical IR Lens for PIR Motion Detector, Hc-Sr501 Adjust IR Pyroelectric Infrared Mini PIR Module Motion Sensor Detector Module Bracket, New Factory Supply Hc-Sr501 Adjust Infrared PIR Motion Sensor Detector Module for Raspberry Pi or Arduino LED Switch Detect Human Moving and so … Overall size: 21mm diameter; Fresnel size: 16mm x 14mm; Focal length: 6~9mm ; Detectable distance: 7m; Viewing angle: 90° Quantity Unit Price 2,500~ $0.30 1,000~ $0.40 500~ $0.50 250~ $0.60 100~ … Leviton OSFHU-ITW Fixture-Mounted PIR High-Bay … We … The HC-SR501 PIR motion sensor is built around the BISS0001 Micro Power PIR Motion Detector IC. Products . PIR Lens, Infrared Lens, Optical Lens manufacturer / supplier in China, offering Cheap Price Infrared Plastic Lens for Ceiling Light (8003-3), Hc-Sr501 Adjust IR Pyroelectric Infrared Mini PIR Module Motion Sensor Detector Module Bracket, New Factory Supply Hc-Sr501 Adjust Infrared PIR Motion Sensor Detector Module for Raspberry Pi or Arduino LED Switch Detect Human Moving and so on. The Fresnel lens is used to see that the two slots of the PIR can see out past some distance. Moto "We make it. Such optics can be manufactured fast and inexpensively in large volumes. The Plane PIR Fresnel lens is primarily used to transmit infrared light. The PIR Sensor module is a pre assembled board with circuits to compare the infrared rays from the object and that of the nearby area like the mounting wall. When a human body or any animal passes by, then it intercepts the first slot of the PIR sensor. A Fresnel lens both captures more IR radiation and focuses it to a small point.
