  • 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.

    Jan 12, 2013 · when i had the idea of building a metal detector, i searched the web for some circuits but couldnt find much without microcontrollers. nothing simple around except those bfo dudes, but thats not performant enough though^^ so is started to work on a circuit on my own. i came up with a fairly simple design with only a few ics.

  • Metal Detector DIY Circuit Electronics Projects Circuits

    The heart of this diy metal detector circuit is the CS209A IC. The metal detector is built with one 100µH coil that has 40 mm in diameter and is made of 50 turns/0.4 mm wire. CS209A has one oscillator wich forms a LC circuit, the inductance of the coil will change when it is near metal objects.
