Title: PIR Plug?
Post by: CAMRAMan on 25 October, 2019, 05:47:55 pm: I'm putting up some LED curtain lights in my hallway. Ideally I'd like them to come on whenever someone is in the hallway. A quick search didn't find anything suitable, so any ideas from where I can get a PIR plug from?

If you buy LED tape with a USB plug you could do also use something like this:

Just a different form factor, same voltage, use an adaptor ? I'd have no problems with using it.

There is, just not as a single unit. so either way you are increasing the component count...

I would support Kim and Grams suggestion, a battery powered PIR unit wired in to the DC voltage side of the LEDs seems like the least component count so far.

If you still want to switch mains voltage, an option (hardwired in) is this:

Alternatively on the DC side of things, there's this which seems less obtrusive...

Not knowing any further details of the load and location of wiring thats about the best I can come up for you for a starter for ten :) :thumbsup:

Post by: CAMRAMan on 27 October, 2019, 11:50:38 am: Thanks for the ideas. For about £17 I've found a PIR sensor that wirelessly operates a remote plug-in socket. It'll do, I spose. My sparky-fu isn't going to stretch to fettling wiring, I'm afraid.
