Electric Field Detector Circuit Using 6 Million Gain Transistor

  • on Tuesday, August 17, 2010

  • This is a circuit that can produce 6 million gain. As well as detecting general electric noise, this circuit can be used to detect “mains hum,” the presence of your hand without any direct contact, and detect static electricity. This circuit is based on transistor BC547. This is the figure of the circuit;


    The mains cable can be located by this circuit by moving it across any wall. The gain is achieved from 200 x 200 x 200. Since the circuit detects very weak electric field, it might look like ghost detector because electric field has weird pattern sometimes.

    Does not work! It won't even pick up cell data from a phone.
