VOLTAGE LEVEL INDICATOR CIRCUIT

In this venture, we are demonstrating how to plan a straightforward Battery voltage Level Indicator Circuit utilizing basic accessible components.battery level pointer




Battery voltage level marker shows the status of current of the battery just by gleaming LED's in series(Red,Yellow,Green). Res LED's Indicates 2 volts, second red LED demonstrates that current is presently 4 volts, Yellow LED shows current is currently 7 volts and Green LED shows that current is presently 12 volts in the battery. In this circuit we have 1k resistors to control the current in the LED's you can utilize 560 ohm resistor with last two LEDs since keep going two LEDs has on top degree of all LEDs that is the reason you can utilize less resistor. This venture clarifies you how structure battery level pointer with hardly any segments. You can utilize this circuit to check vehicle battery or rearrange er. This circuit encourages you to expand the existence time of the battery.

Circuit 2 with movable volts estimation 


you can change this circuit effectively by expanding and diminishing the LED's and resistors. On the off chance that you need to change this circuit as movable, at that point please utilize variable with it as appeared in the chart.

In this circuit I have utilized only a 5 k potentiometer to alter the estimation of volts. Along these lines this circuit become progressively adaptable now you can gauge even till 40 volts.


Battery Voltage Level Indicator Circuit Principle

The present level pointer circuit work with the assistance of roisters just as LED's. Resistors controls current in arrangement with the assistance of LED's As current go through the first LED's present worth log jam and that is way second LED shines on more volts as contrast with first LED and thusly third LED required more volts to sparkle as contrast with second drove. Thusly next LED required more volts to shine as contrast with past. we are utilizing 1 k resistors just for ensuring LED's since LED can hold up under just 1.5 to 3V.

The most effective method to Build a Voltage Level Indicator with a Zener Diode

battery level marker 

In this circuit, we are demonstrating how to construct a voltage level marker with zen-er diodes. In this task we have utilized 4 zen-er diodes of various forces to make an ideal voltage level pointer.

A typical diode goes about as a short out in forward predisposition condition while in turn around inclination condition, it goes about as an open circuit. A Zener Diode has a breakdown when a specific voltage level is come to. The voltage that go through the zener diode is known as the breakdown voltage of the zener diode. In the event that a zener has a breakdown voltage of 5.1 V, after 5.1 V or more prominent is applied to it, it will cross the voltages which control on a load.In this circuit, the kind of zener diode we have utilized are:

1N4728: 3.3V

1N4734: 5.6V

1N4739: 9.1V

1N4742: 12V

As per zener Diode first LED will sparkle on 3.3v second LED will gleam on 5.6v third Led will shine on 9.1v and keep going Led will sparkle on 12.1 volts. Along these lines you can expand the no of zener and no of LEDs to make it progressively reasonable.
