Next is the schematic of another version of the metal detector module that has a circular coil etched on the printed circuit board. In this near-identical design, you can see an annunciator LED too. This is the photograph of the second version (I don’t have one handy yet):

Simple Metal Detector Circuit Diagram using 555 Timer IC

May 14, 2015 · This RLC circuit is the metal detection part. Now as mentioned earlier in previous section, a metal core inductor has a high inductance value over a air cored one. Remember the coil wound here is a air cored one, so when a metal piece is brought near the coil, the metal piece acts as a core for the air cored inductor.


Locator is just the thing for you, there are a number to choose from. Most work on the L-rod principle but there are other types since the term ‘Long-Range Locator’ covers any device that will pinpoint metal from a distance (usually measured in yards or miles) as opposed to a metal detector which only works in close proximity (a few inches).

Easy to build pulse induction metal detector with DSP ...

Pulse induction metal detector with DSP Introduction to metal detection. Most metal detectors work on the fact that metals in a magnetic field change the behavior of the field. There are two general approaches to detect these changes. In one approach, an alternating current is provided to a transmit coil.
