PIR sensor enclosures

 I’ve gotten a few questions about the PIR sensor enclosures I use. My sensor of choice is the SR602 it accepts a supply of 3.3-18 V and outputs HIGH (3.3V) for 2 seconds when movement is sensed. The form factor is the real reason I prefer it, though. The circuit board for the SR602 is circular and fits perfectly inside a 1/2” PVC fitting.

My enclosure is based in no small part on the work of Halstaff, the great one. Mine has fewer parts and a slightly different form factor, but he certainly inspired me. If you haven’t seen his videos, do yourself a favor and check out is work. He’s sadly no longer with us, but I like to think of him as still working with the haunt community (just perhaps from the other side).
