Thread: motion sensor killswitch?

Tweet

I've actually been thinking about this a lot. I may want to modularize these components.

First build a rig with just the relay and outlets (one for NC and one for NO). Then plug that into a rig that just has an input with a motion sensor and an output. That way I'm not stuck to the motion sensor for the switching between the two.

I was at Big Lots! this evening looking for tonic water for glowing Jello and I saw a remote controlled switch for 120V AC that'll control up to 1000W for only $12. If it wasn't a 10 day pay period that fell on rent day, I would have totally got one. Instead, I hid one and hope it's still there when I go back.

Yeah, the Valley 6 is still open. We also make the trek out to Whidbey Island occasionally to hit the Blue Fox DriveIn, but that's WAY OFF TOPIC.

On topic, I found something called the Super Switch at Harbor Freight, switches 3 separate outlets with one remote. Add some relays and motion sensors and voila! I'll have a lightshow.

Solder a second 2 wire AC plug to the two commons of the relay. This goes to unswitched AC power that is always on.

Solder wires to the two NO contacts on the relay and hook them to an AC outlet.

make sure to use heat shrink on your relay connections so that they don't touch.


Then just plug your lights into the outlet.

I usually buy a deep electrical box to put everything in and keep all the electrical connections away from little fingers.

success! it worked just like you said except i had to hook my outlet up to the NC as i wanted the light to be on first, then off when the sensor was tripped. but it works like a charm.
thank you so much for your help

No Problem
