Friedland PIR Wireless shell / cheap in B&Q
6 May, 2012 - 09:46
Just come across these that B&Q are selling off at £3 each (picked up some last week)
I was thinking more of using them as a plastic shell, maybe with a HAHnode in them rather than the pcba itself, but I thought I'd share the discovery with you.
The external dimensions are 10cm x 6.2cm x 4.4cm tapering to about 3.5cm (including the depth for the sensor)

hiding in plain sight...
I picked up a couple of those as well for the same reason, ie hiding an HAHNode in plain sight.
I think three AAA, one on one side and two on the other, an maybe even a suitable motion sensor (4.5v working sensors would be easier to find I think)

Any idea what the wireless frequency is, it would be good to try and decode it and link it to Derek's wireless to serial interface.
