Mar 10, 2021 · 7,049 views. In this tutorial, we are making a useful project of a non-contact AC voltage sensor circuit using LM358. LM358 is a dual op-amp IC, it has two operational amplifiers built on a single chip. The circuit is simple, inexpensive, and only using a few c antenna, LED, Non Contact AC Voltage Sensor Using LM358 - Circuits DIY Mar 10, 2021 · This circuit can be operated on low voltage like 3V DC but an LED requires a minimum of 3.6 volts DC to operate for bright light due to which we are operating this circuit at 4.5V DC.The FLK2ACV is a VoltAlert™ AC Non-contact Voltage Tester, designed to be pocket-sized and easy to use. The 2AC tests for energized circuits and defective grounds, whether it's for an electrician on the factory floor or the do-it-yourselfer around the house.Mar 10, 2021 · 7,049 views.
