This work reveals the presence of an Electronic gadget where it is misused/restricted/prohibited in the premises. The objective of this work is to detect the electronic gadget, which is exhibiting magnetic field even when it is in Power off/Airplane mode. This detector concentrates only on some major parts which are used in the mobiles/electronic gadgets for the purpose of detection and then indicates to the alert system. We have many systems to detect the signals receiving or transmitting from the device i.e. in-active condition. By using this detection circuit which has magnetic field detecting sensors, we can identify an electronic gadget which exhibits the magnetic field. By using this sensor, the misusage of electronic gadgets in the prohibited areas can be restricted/ eradicated.
