PIR sensors, weatherproofing | PICAXE Forum

· The theory is simple. The PIR sensor + circuit senses changes. The fresnel lens is a multiple lens which amplifies sections so that a 'hot' object moving across causes high-low (on-off) due to focus. These signals (above a threshold which may be variable or AGC) are converted to pulses. These pulses are often counted to try and reduce false ...

PIR sensor protective lense — Parallax Forums

· Also download their F resnel lens guide. Consider using a basic PIR element behind a fresnel lens acting as a cover, perhaps with the smooth side out toward the work area. Eclectic E6000 adhesive (Goop) sticks to it passingly well, especially if the bond surface is roughed up a little and well cleaned. Or the lens could be clamped with a gasket.

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 ...

PIR through frosted plastic? - Sensors - Arduino Forum

· 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. So as you move across the field, the heat it picks up goes in and out of view. This is how it detects a warm body. So you cannot use a cover that is translucent to IR. It must be clear for IR light, although it can be opaque to visible light, as the PIR covers …

· 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 ...
