Ac voltage detection circuit
WebSep 23, 2024 · This Non-Contact AC Voltage Detector Circuit has the wire through which it senses the voltage. We connect the wire with the base of BC547 transistor Q3 which detects the EMF of supply. Then it gives the signal to another transistor Q2. Thus signal gets amplified and further goes to transistor Q1 which in this circuit is working as a switch. Web2.4in Non-contact Circuit Volt Tester Digital Smart Multimeter Voltage Detector.
