Arduino Based Metal Detector for Military Security

Abstract

The world's biggest and fastest-growing manufacturing sector is the electronic industry. Metal detectors are an electrical
instrument that fascinates people. When properly designed and deployed, the world will be able to identify any metallic substance
travelling by or approaching in close proximity. As an alert, this function would act as a security check for hazardous metallic
stuff. Without the addition of a metal detector, no security system will be optimal or complete. A metal detector included within
the gadget may detect metal items such as coins, nails, keys, and gold. This metal detector can identify some types of metal, particularly iron-containing metals (ferrous metal), even if they are hidden behind a halfinch of dry well or sand. The goal of this
project is to design, create, and build a simple, inexpensive, and effective metal detector. The oscillator was used to build this metal detector. The primary goal of this project is to create a metal detector using electrical components that are readily accessible and inexpensive. Following the first and second world wars, one of the earliest wide spread applications of metal detectors was the identification of land mines and unexploded bombs in a number of nations. This project provides an overview of the operating principle and uses of metal detectors.
