Occupancy sensor: not wall mount

I have a stand alone wardrobe -- Big with large twin sliding glass doors. When you slide open either door there is a tiny motion sensor inside in the middle of each compartment that turns on the hanger bar light.

I have never been able to find something like this. The sensor is wired back to a small control box. The box has two cords: one to plug into an outlet and another to power the 110v hanger bar light. My unit has two of them.

It would make a great override for my hot water recirculation system -- few other uses I can think of. Understand I can always use one that looks like a switch .. but you can't really hide them. This is tiny

I'd be interested in using that type of switch to turn on a hot water recirculating system. My idea is to sense motion in the kitchen or one of the bathrooms, and then turn on the recirculating system only when someone is likely to need hot water. Having each cycle timed (maybe 10 minutes max) would be even better.

Yes -- it's amazing that you can't get a simple devise. Yeas ago I linked the recirculation pump to the main bath light ... but, that was before all the dimmers.

Doing the manual button is a pain .. even the smart pumps run too much.

There are tons of occupancy sensors out there that have an extra set of contacts in them. They're used to turn on the lights, of course, but to also turn on A/C or heat to the space. Wouldn't one of those work?

Can you link to something that's not a wall outlet type.

Think I found a german one that is used in kitchens (small sensor) with wire to transformer -- It's low volt to run LEDS ... but it looks like it will power out where I can have a relay ... it has a 30 second fixed delay. That actually would work.


My plan was to hide the sensor inside the bath door trim to kick the pump on as someone enters the bath. Going direct to the sink may be too fast for the pump to get hot to the sink .... but most times that's not what occurs. I like low volt -- as I could run the low volt wire back to the mechanical room -- have the relay there next to the pump control.

This isn't "tiny" but does what you're looking for.

Google for a microwave motion sensor. This is the new style that the lighting manufacturers are quickly converting to. They're pretty tiny. You'll have to sort out some way to connect it to your light source. Typically, they're connected to and powered by the driver. Most are configurable for your desired timeout, delay, etc...
