Designed by creator Aaron Rasmussen of Engadget, the Mr. Ghost EMF Detector lets you know if there are any harmful rays in your home.
This detector is an antenna that you can attach to your iPhone through the headphone jack and works with a free app to sense any and all EMF rays in your immediate vicinity. Use it to check out how much EMF, or electromagnetic radiation, is leaking out of your home appliances; they don't even have to be on, it's enough that they are plugged in. Also, this device doubles as a ghost hunter because everyone knows that ghosts release EMF rays as well.
