Use frequency in the range of 100..200kHz. Measure the frequency, using the MCU. If the metal is ferromagnetic (iron, nickel, etc) it will cause decreasing of the generated frequency. If the metal is not ferromagnetic (copper, aluminum, gold, etc.) it will cause increasing of the frequency. Notice, that some temperature drift of the frequency ...

The metal detector operates based on the principle of electromagnetic induction. The LC sensor detects the metals using one inductor coil and one capacitor grouped in a parallel circuit. The LC circuit works like an electrical resonator, and it oscillates at the resonant frequency of the circuit using stored energy (Signal A).
