Outdoor Dual Beam w/Piezo Sounder
I know this is meant to be an outdoor motion sensor but I can see so many different applications for this product. First of all, you could use it for its intended purpose such as putting on the inside of a gate or fence to sound an alarm when someone breaches your space. You could also place out near your plants that deer tend to eat to scare the deer away. If you leave your garage door open, you can keep various critters from coming inside your garage.
Some other useful applications include practicing your cat burgular skills by setting up a couple in your family room and performing various gymnastics moves to circumvent the IR beams.
When it comes to work you could always use these as a security alarm for when you’re surfing at work and don’t want someone to sneak into your office or cube. Better yet, you could place this inside a stall in the bathroom… imagine the hilarity when someone who really has to go opens the door and gets blasted by a 70dB piezo sounder!
