Hey everyone. I have a 360-degree PIR sensor in my garage which activates the lights upon detecting movement. This is situated in the far corner of the room, opposite from the inner entry door. It replaced a more directional sensor that died (and was crap anyway).
My issue is, the inner door seems to be right on the edge of the detection range. I've had a look and there are no sensitivity adjustments on the unit itself (just an on-time and ambient light level detection).
I'd rather not move the PIR if I can help it. Is there a way to "passively" increase the range. It doesn't need 360-degree detection as it's in a corner against two walls, so everything 180-degrees behind the sensor doesn't matter.
