Build Your Own Metal Detector with an Arduino

The inductor of the above tank circuit forms the detector of the metal detector (a large coil of wire). When metallic material approaches the center of the inductor (the detector coil), it enters the magnetic field created by the inductor. This changes the magnetic permeability of the inductor's core, causing the inductance to change. The ...

Simple Metal Detector Circuit - electroschematics.com

The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor and a search coil – and of course the batteries.

Metal Detectors - Theory and Practice - VLF, PI and BFO ...

Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.
