PIR through frosted plastic? - Sensors - Arduino Forum

06/05/2021· 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 …

PIR motion sensor lens cover - need help - Sensors ...

06/05/2021· 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 ...

PIR sensors, weatherproofing | PICAXE Forum

30/04/2014· 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 ...
