Metal detector circuit diagram 5


Posted on Feb 5, 2014

The metal detector circuit consists of oscillator and sound-light alarm circuit, and the circuit is shown as the chart. Oscillator circuit consists of inductor L, capacitor C1, sensor switch integrated circuit IC1 (includes oscillator, detector and comparator circuit, etc. ) and the peripheral components. Sound-light alarm circuit consists of four

NOR gate integrated circuit IC2 (Dl ~ D4) and the light-emitting diode VL, speaker BL and other components. R1 ~ R6 select 1/4W carbon film resistors. C1 ~ C4 select ceramic capacitors. VL selects 5mm high-brightness light-emitting diode. V uses S9013 or C8050 silicon NPN transistor. IC1 uses TDA0161D sensor switch integrated circuit; IC2 selects CD4001 four NOR gate integrated circuit.
