small scale motion sensor for display case??

Ok, is there a motion sensing device out there that I can use in conjunction with some 'puck' style , under cabinet lights that I got , for use inside a bookshelf/display cabinet? The idea, is to have the lights come on whenever someone is standing directly in front of the bookshelf, so they can view my collection of model cars!, and then turn off after a set amount of time...I KNOW theres gotta be something out there that can do this!! Thanks, Mark

I am not sure if this will work with a transformer type puck light, but how about just a regular room occupancy sensor light switch. Just mount it in the back of the cabinet. I would check to see if it can handle transformer type loads.

How about using a 'proximity switch'. When You stand near the sensor, a device will come on, be it a lamp, motor, etc. I made one years ago, in the day pre-transisters. Now that are very simple to make. Maybe RadioShack sales one? Here is a website that has plans for a simple one. The components.

guitz,

I think bink has the right idea to use a proximity sensor.
I have used them and they will work well for what you want to do.
They are what is used on automatic flushing toilets, sinks and hand driers.
You could build one or if you want to purchase it you would need to get it at an industrial electrical supplier.
