I've been toying with the idea of replacing the lightswitch in the bathroom with a PIR sensor so I don't have to remember to turn the lights off.
Apart from sensors designed for burglar alarms the only one I've seen that comes close to what I had in mind is at Maplin. Trouble is, the blurb says it's not suitable for bathrooms, or for switching fluorescent lights (not entirely sure why)
Has anyone got any idea where I might find something along those lines?
