I'm trying to develop a device that can record athletes individualy while running on a track.·The purpose of this design is to keep track of·lap times.·There's an infra-red beam breaker that can do this, but it is only useful for an individual athlete. I was thiking about placing a magnet on the athletes·shoe·or any object that a particular sensor can detect individually. If this is possible, what kind of sensor can do this? Does anyone have any ideas?
