Cell Phone Detector: This is a simple circuit which helps to detect the presence of an activated cell phone by detecting the signals in the frequency range of 0.9 to 3GHz. It helps in tracking mobile phones particularly in examination halls or important conferences. It can also be used to detect the mobile phones of spies or in case of unauthorized data transmission. The radius of this detector is 1.5 meters.
