· The Pi Metal Detector Circuit works by making use of a Raspberry Pi’s GPIO pins to detect the presence of metal objects. A small coil is connected to the GPIO pins, and when a metal object passes near the coil, an electrical current is generated which is detected by the Raspberry Pi. To create a more precise metal detection system, two

· The VLF metal detector circuit diagram is quite simple. It consists of two parts: the transmitter, which creates the electromagnetic field, and the receiver, which receives signals from the transmitter. The receiver then sends these signals to the detector circuitry, which processes them and determines the location of any metal objects.
