(Re-)Installing and modifying a PIR module

A while back I ordered a cheap 230V PIR of AliExpress to control the light in our washing room because my housemates always forget to turn it back off. I came across a nice model that didn’t use the normal bulky (outdoor-ish) case but rather used a small external eye you could integrate in a ceiling. And because the room has a suspended system ceiling that was perfect.

When I got the device I opened it up, looked at it and thought “Yeahhhh, good enough”.👍 Then I quickly connected it and instead of drilling a whole I just sneaked the wire to the eye/PIR on the side of a panel and just suspended it there. And it worked fine! It turned on the light when you walked in and now most of the time the light was off. Win!😎
