8 Low Battery Voltage Alarm indicator circuits using SCR transistor IC
Both circuits can be used to detect the voltage level with a comparator circuit using LM339. The LM339 Quad Comparator is another type of op-amp specially designed for voltage-sensing circuits, so it is very accurate. It can sense a drop in voltage of 2 or so millivolts, for example when the voltage drops from 12.400V to 12.398V.

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. We use a single zener diode in this circuit to function as our voltage level indicator.
