PIR Fresnel Lens Passive PIR Lens, Infrared Fresnel Lens ...

Buy PIR Fresnel lens, flat infrared Fresnel lens, passive PIR Fresnel lens replacement with HDPE material at the lowest price for motion sensor and detector use. The Plane PIR Fresnel lens is primarily used to transmit infrared light. The passive PIR lens material is made of milky white flexible, thick High Density PE with UV protection.


PIR Fresnel lens, PIR sensor lens from ETAY Fresnel Lens ...

PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This PIR fresnel lens is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.


PIR motion sensor lens cover need help Sensors ...

· I am using a couple of cheap ebay PIR motion sensors with the classic bubble dome. I think this dome is ugly and I would like to substitute a different lens cover. Here is an image of the device, the idea is that the opening at the top is to be a band of some material that won’t inhibit the 3 motion sensors inside. The bubble dome and other motion sensors use a semitransparent fresnel lens ...

using PIR sensor without lens? | Forum for Electronics

· Instead of a lens you an use a grid. Use a dielectric like Teflon to make a grid. Lens or grid are used to modulate the input temperature due to an object moving across the field of view. Only these changes are detected and amplified in the sensor circuit. A PIR sensor can detect the presence of an object but its response is unstable due to 1/f ...
