Motion sensor hack

I know Halloween is over, but this hack can control a lot more than just a spooky prop in your yard. You can usually pick these motion-detecting lights up for a bargain at the local home goods store. Just be careful, this is a high voltage hack!

Yard-light motion sensors are a cheap and easy way to add some automation to your haunt. Just hook up power to the sensor, hook the output to an outlet, and you can control anything that runs on 120VAC. But what if you want to control something else? It turns out it’s pretty easy to modify these motion sensors so the output just acts like a normal switch or button.

  1. Fun inexpensive hack! I played with these years ago. One out by the garage I screwed in a thread-to-prong adapter which had a Radio Shack wireless intercom plugged in with the ‘page’ button taped down. The other intercom was in the house on standby. Any summer prowlers looking for an easy score with cars/garages down the alley, I was alerted… chased several off over 4 years.
    Then I made a portable one that could plug in anywhere, clamp it in place, plug anything into it. I pluged in a 9V transformer for a 9V personal 110db alarm. Our mail got stolen once, our vacation itinerary was in it. Neighbors informed of the situation made piece of mind along with the alarm in the house.

  2. does anyone know how to manipulate the timer on a motion sensor? I’m connecting my motion sensor switch to a lamp, but the light turns off 15 seconds after someone has left the room — I want the delay to be more like 3-5 seconds. thoughts? thanks!
