DescriptionThe Non-Contact Voltage Tester Circuit is made of high-quality material. It is useful. It can be used as a contactless AC live line detector or as a safe tester, which can detect whether the line is live or not without any physical contact with the line.
The Non-Contact Voltage Tester circuit uses a counter IC 4017. As in the circuit, a probe or antenna (a wire) should connect to pin 14 of the IC clock input of the IC. The probe connected to pin 14 detects the presence of an AC main phase supply near the line and if the line has any pulsating EMF (an active line) the LED flashes and indicates whether the line is charged or not.
