battery level indicator using pic

Aim of the project:

To prepare a system that can operate devices even in the absence of electricity. When the electricity is not available the discharging of a battery after digital to analog conversion is used to operate the devices. In combination to this battery level has been displayed on the LCD.

Making:

The inverter circuit uses only four resistors and two transistors, and one transformer. Transistors could be NPN or PNP depending upon the polarity of battery. The DC input is given to a DC to AC conve ....etc

At many situations we need to display the amount of battery charge through some kind of indication methods like LED dot display or LED bar display. Here CG comes with a battery charge indicator circuit using LED dot display. This battery power level indicator circuit is build around LM3914 IC. It is able to sense voltage levels and is capable to drive a display of 10 LEDs in dot mode or bar mode.
We have already posted a temperature level sensor using this same IC (LM3914). This can also be used as a low battery voltage indicator circuit as it ....etc

Battery level indicator indicates battery status only by bright LEDs. For example, six LEDs are bright means that 60% battery capacity remains. This article explains how to design the battery level indicator. You can use this circuit to check the car battery or the inverter. So by using this circuit, we can increase the battery life.
This circuit is designed based on lm3914 IC (integrated chip). This IC is LED Spot / Bar Display Driver.

Battery level indicator Circuit principle:

The heart of this battery level indicator circuit is ....etc

battery level indicator project using 8051 microcontroller

Here is a easy to build low battery level indicator circuit that produces a visible indication by flashing a LED when the battery voltage drops below a predetermined voltage.The circuit is based on Panasonic s IC MN13811G and a efficient flasher based on transistors Q1&Q2.Here when the battery voltage drops below 2.4 V the output of the IC is activated and the flasher starts flashing.This circuit here is an ideal one for monitoring the level of all types of 3V batteries.The circuit ....etc
