Motion detector plus?

[tj Wise]

I am looking for a motion sensor that will not just activate a light, but also make some noise or even flip on another device that is plugged in to it. My googling has failed me so far. Thanx! Oh, I am also pretty cheap, lol.

If your really cheap just throw some sea shells and such on the walkway where the motion light turns on...:rolleyes:

If someone breaks the invisible beam it set off a chime in your house.
