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 …

· Just Google ‘fresnel lens for pir sensor’ and you will get some hits, but you will have to check the details of the size, etc. Won’t break the bank if it doesn’t work. A couple of quid from eBay.
