Its really this period of the decay that the circuit is trying to amplify & detect, because this decay signature changes when the metal detector is above a piece of foreign metal as the figure posted by "Voltage Spike" suggests. The voltage at the non-inverting input (call it Vx) to IC4 is a virtual ground, held at Vx = 9V.

The analog part of the schematic is classic, is inspired by SPIRIT PI 2.0 ESP32 (N.E.C.O) schematicand often used bya lot of people who are manufacturing their own metal detectors. But idea was to replace the digital part (usualy ESP32, ATMega8 or Arduino Uno boards) with Raspberry Pi Pico based on RP2040 microcontroller.

A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881.

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 metal detector consists of two parts, the detection coil and the filter circuit. The detection coil is the core part. After the coil is energized, a magnetic field will be generated, and if metal enters the magnetic field, it will cause the magnetic field to change, thus judging that there are metal impurities.

Open-loop sweep, closed-loop sweep, and discriminator-aided acquisitions are the methods that are covered. The phase/frequency detector uses discriminator-aided acquisition and is the most popular choice. Clock-recovery circuits cannot use phase/frequency detectors. Consequently, these circuits require an acquisition aid.
