AC Voltage Detector DIY - PCB Tutorial

■ JLCPCB Prototype for $2(Any Color): https://jlcpcb.com

This circuit is a Voltage Detector and works thanks to three BC547 transistors. The operation of the circuit is very simple: The small antenna is able to pick up the electromagnetic wave (EMF) emitted by the electric voltage.. this signal is amplified by the first two transistors, the third transistor acts as a switch and when signal reach its base it becomes closed switch and turn on the LED.
