Re: Occupancy PIR detectors



Have we had a picture of this wonderful PIR posted yet?

Dang!
 
Been playing with the one I have here today too ... I stuck the one I have through a hole in the loo ceiling as I'm cutting holes there for halogens anyway and had similar results to you. Seems sensitive enough to trigger repeatedly whilst reading the CPC catalogue in the bath!
 
Simon ... looks like you'd better either let us all know of a source for them or prepare yourself for a "group buy" through you.

I've just tested one of the 12V occupancy PIRs that I've mentioned in a recent thread.  Connected it directly to HomeVision's Port B and it works without connecting the PIR's open collector output to a voltage via a resistor.  HomeVision's Port B already has +5V via 2.2k resistor built in - so everything is kept nice and simple!
 
The PIR is very sensitive :o)
Once it's been on for a few minutes and stabilises, it detects brilliantly.  Very pleased with the performance, and also relieved since I'm relying on these PIRs for automating lighting and heating and other occupancy related stuff.
 
Yipee!
