Metal Detector Elektor Magazine
Metal detectors generally operate on the basis of one of the following technical prin- ciples: BFO (beat frequency os- cillator). In this system, the inductor in the search head is part of an os- cillator, whose variable out- put frequency is mixed with another, fixed, frequency ob- tained from a second oscillator. The difference (beat) frequency falls within the audible range. When the search head is brought near a metal

Arduino Metal Detector Project with Code and Circuit
06/01/2018 So here in this Arduino Metal Detector Project, we have to find the inductance of the coil to detect metals. So to do this we have used LR circuit (Resistor-Inductor Circuit) that we already mentioned. Here in this circuit, we have used a coil having around 20 turns or winding with a 10cm diameter. We have used an empty tape roll and wind the wire around it to make the coil. Circuit

Metal Detector using a 2 Pulse Induction Coil
A sampling circuit in the metal detector is set to monitor the length of the reflected pulse. By comparing it to the expected length, the circuit can determine if another magnetic field has caused the reflected pulse to take longer to decay. If the decay of the reflected pulse takes more than a few microseconds longer than normal, there is probably a metal object interfering with it. The ...

Although this is done in most commercial and home made metal detector circuits, it is less than ideal.

We will postpone this problem to the paragraph about the power supply and will now only assume that our ...
