How to Build a Metal Detector Circuit

In this project, we will demonstrate how to build a simple metal detector circuit. The device we then build will function as a metal detector that can scout out metal objects, such as coins, nails, keys such as car keys you may not be able to find, and even gold if you're looking for in a beach (though this one may not have industrial strength).

Simple Metal Detector Circuit Diagram using …

In this project we are going to design a simple metal detector circuit. There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 Timer IC. Before going further we need to understand concept of inductor and RLC circuits. Let us first talk about inductors. Inductors are nothing but coils of enameled ...

Build Your Own Metal Detector with an Arduino …

Traditional BFO (beat-frequency oscillator) metal detectors overcome this problem by incorporating another tank circuit with a fixed frequency equal to the frequency of the detector tank circuit without the influence of any metals. Then, taking the difference between the two frequencies will isolate the fluctuating frequencies of the detector circuit and bring it down to an audible range.

Detector (radio) - Wikipedia

In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations transmitted information by radiotelegraphy.
