Solved Design a voltage level indication circuit By using Circuit Diagram A simple electronic part such as an LED can play an important role in displaying and monitoring the condition of this AC mains voltage and warn us of a possible electrical hazard. Here, I have explained exactly how to make ac voltage indicator using leds through a construction of a little electronic circuit. A voltage sensor circuit is a circuit that can sense the voltage input into it. If the voltage reaches a certain threshold, then an indicator, such as an LED, will turn on.
Description This circuit, designed on request, has proven to be useful to indicate when the voltage in a power supply line is changing from 120V to 240Vac. It can be used in different circumstances and circuits, mainly when an increase in ac or dc supply voltage needs to be detected.

We have many ways to indicates an AC line. A good way, the AC mains voltage indicator circuit with a LED. It may be the best choice. It save and to be easy.
This is four circuits of LED voltage indicator are simple and easy to builds for check voltage battery and others, use as zener,transistor,LM339 and more
Make an LED AC Voltage Indicator Monitor Circuit Circuit Diagram
In this circuit, we will show how to build a voltage level indicator with a single zener diode. A voltage level indicator is a circuit which can show if the voltage input into a circuit is greater than a certain threshold level. If the voltage is greater than a certain level, then an output such as an LED can light up or a buzzer can sound off.
