ABSTRACT
Abstract: This system proposes metal detector by using PIC microcontroller interfacing with PC. The system uses PIC microcontroller as the main controller whether the detected metal is ferrous metal or non-ferrous metal. Among various types of metal sensors and various types of metal detecting technologies, concentric type induction coil sensor and VLF (very low frequency) metal detecting technology are used in this system. This system consists of two configurations_ Hardware configuration and Software configuration. The hardware components include induction coil sensors which senses the frequency changes of metal, a PIC microcontroller, personal computer (PC), buzzer, light emitting diode (LED) and webcam. The software configuration includes a program controller interface. PIC MikroCprogramming language is used to implement the control system. This control system is based on the PIC 16F887 microcontroller.This system is mainly used in mining and high security places such as airport, plaza, shopping mall and governmental buildings.
