How To Design A Battery Level Indicator circuit? By Hamza Iqbal Updated on October 28, 2019 In the recent century, everything that is used in day to day life is electronic. Most of the electronic components that are small scale use a battery to power themselves up.
Voltage Level Indicator Using LM3914 Dot/Bar Display Driver IC
In the proposed LED battery voltage monitor/indicator circuit all the four opamps have been used, although a few of them may be eliminated in case they are not required or depending on the specs of the individual users. As can be seen the circuit diagram, the configuration is simple yet the outcome too effective.

Voltage Level Indicator Using Zenor Diode YouTube
This LED DC voltage indicator circuit is a voltmeter, rather than simply a battery tester. As such it may measure voltages as low as 3V. It utilizes venerable LM741 operational amplifiers applied as comparators that drive LED indicators. Voltage thresholds are 3, 6, 9 and 12V. Above each incremental threshold an additional LED turns on.
high voltage indicator circuit diagram Wiring Diagram and Schematics
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.
