PIR through frosted plastic? - Sensors - Arduino Forum

· The sort that a PIR sensor uses ( wavelength 8-14 micrometres ) and the sort an IR remote control uses (wavelength micrometres ) are miles apart. So you need a bit more detail on that statement. polymorph November 5, 2014, 7:40pm #7. There is another problem: A PIR lens consists of a bunch of fresnel lenses. So sometimes your body heat is focused on the detector, sometimes it is not. …

PIR repair | DIYnot Forums

· The plastic is actually a lens which focuses IR radiation from the room into carefully designed 'zones' on the IR receiver. Replacing it with a piece of ordinary plastic isn't going to work I'm afraid. These lights are so cheap that it's not worth the hassle. Bin it and buy another for a tenner.

How to replace or repair a motion sensor PIR lens - iTecTec

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? I am not asking where I can buy this part (and I am reaching out to the manufacturer now that I have the part name); I just want to know whether it is possible (and worth my time) to replace this part or the whole item. Alternately, can I repair it? Is there some ...

- Testing and Playing with PIR sensors ...

· In one of my current projects, I’d like to use a few motion or proximity sensors, also known as PIR sensors. PIR sensors, or Passive Infra Red sensors, can be great for Arduino and Raspberry Pi projects, and can be bought really cheap – I only paid about a dollar per sensors in bundle of 10 PIR sensors from eBay, but you can get them really cheap at places like Amazon or AliExpress as well.

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 performance, however other devices can be used to ...

Motion sensor cover has a hole in it. What to do? - Misc ...

· The “bubble” is a fresnel lens covering the PIR sensor. I’m not 100% sure what that does as far as the sensor’s functionality, it probably focuses incoming IR light in some way that improves the sensitivity. So the sensor could still work without it but maybe not as well as it used to. And your point re: water entry into the device is a good one. If it were my camera, I’d probably ...
