Metal Detector using Arduino - Engineers Garage

Metal detector is a device used to detect the presence of a metal in its proximity without touching it. This project explains the concept of detecting the presence of a metal using the method of inductive sensing. The basic concept used is that the presence of a metal can vary the inductance value of an inductor. The prototype discussed here is a modified version of an inductance meter, which ...

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.
