OBJECTIVE:
Aim of this project is to find the unknown object identification and alert system.
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The electromagnetic field is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The magnetic field disappears when the current ceases. By using this, objects other than iron metal can be found. This concept can be implemented using microcontroller.
To generate the electromagnetic field the 2000 turns of copper coil which is supplied through relay and when it found other metals the controller it will produce sound using buzzer.
This project is implemented using RF Transmitter/Receiver, PIC micro-controller, and 2000 turns of copper coil.
