Occupancy switch

[rwb]

Been asked today to fit some sort of occupancy switch to customers living room lights, the lady in question is disabled and has very limited amount of movement so I don't want anything that is going to keep switching the light off if she is immoble for any amout of time. does anyone have any ideas or knowledge of a switch that maybe suitable?

Not sure what you are trying to achieve with the occupancy sensor ie light on all the time the room is occupied or only if light levels fall below a predetermined level

Most occupancy sensors are PIR based although there are some that sense sound as well they will turn the lighting off once no movement or noise is detected for the set time. This would be difficult with the circumstances you list

If you Google "occupancy sensors" you may find one that suits your application

The only other suggestion would be a remote controlled light switch

I would go with a remote, For example:

Remote control dimmer switches for remote control lighting in your home.

Ashley PIR 's are programable with reset times 2 = 30ins , they can also be controlled by hand held remotes ,

Thanks Chaps, remote maybe the way to go i will put it to customer tomorrow.

Microwave detectors are much more sensitive than pir's. May be usefull if there isnt much movement.

i have the remote ones in the lounge and bedroom just because i am lazy
the home easy ones are quite good as you can control sockets boilers etc with them. programmable too. I am getting the sms unit so i can turn the lights on when we are away from a standard text.
