Metal Detector Circuit Diagram and Working. The figure shows the circuit diagram of metal detector . The 555 IC timer here acts as a square wave generator and it generate pulses with frequencies audible to human. The capacitor between pin2 and pin1 should not be changed as it is need to generate audible frequencies.

Now the two frequency will be different, there will be no cancelling and the radio produces a hissing sound. This means a metal object is detected.

به خواندن ادامه دهیدA 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.
