Re: Room occupancy detection and door opening/closing - 1-wire or wireless solution?

[Kevin Hawkins <yahoogroupskh@xxxxxxxxxxxxxx>]

The Phaedrus Beambar does this..

It can be positioned diagonally to reduce width - but it's still a
fairly large/ugly piece of kit and requires wiring on both sides. What
we really need is a dual beam version that is cosmetically nice -
ideally fitting recessed into a circular rebate.

I'll be playing with Pulsars (beam stress sensors too) when I finally
get around to improving room occupancy http://www.sureaction.com/pulsor.htm

Idrateks' Cortex application has a layer of 'smarts' that helps with
occupancy counting as it knows about paths into and out of rooms,
