• Metal Detector

    2016-1-1 · A less common form of metal detector is based on pulse induction (PI). Unlike VLF PI systems may use a single coil as both transmitter and receiver or they may have two or even three coils working together. This technology sends powerful short bursts (pulses) of current through a coil of wire. Each pulse generates a brief magnetic field.

    This metal detector is based on an Arduino or ESP32 microcontroller and a smartphone. It is easier to make than a VLF metal detector because you do not need to adjust the coils and adjust the balance of the coils. In this metal detector we only use one coil that at the same time is the transmitter coil Tx and the receiver coil Rx.
