In this Studio I built a cell-phone tracking device which would be used by emergency responders to locate survivors trapped under rubble after a disaster situation. It can be difficult to locate people when they are out of sight and unable to move, pinned under tons of concrete, but this project aims to make that easier. Almost everyone carries a cell phone in their pocket, and these cell phones are constantly broadcasting their existence to anyone who will listen. Using a Bluetooth Low Energy sniffer connected to a directional antenna, this device will determine the direction and strength of these signals, which will lead rescuers to the location of the victim. A device like this will change the way emergency responders work for the better, by allowing them to find survivors easily using a cheap and compact device.
