The document describes a digital fuel level indicator that uses a microcontroller to show the exact amount of fuel remaining, unlike traditional fuel gauges. It has two main parts: a sender unit in the fuel tank and an indicator. The system includes a PIC microcontroller, LCD display, analog fuel gauge, float in the petrol tank, A/D converter, and battery. Potential enhancements include programming the microcontroller to estimate accurate distance to empty based on past mileage and fuel usage data, and adding remote engine shutdown capabilities in case of vehicle theft.

3. Introduction
 Digital fuel gauge, which shows the exact amount
of fuel remaining in the fuel gauge as compared
to the previously used gauge meter in which a
needle moves to give a rough estimate of the fuel
left.
 A fuel indicator is an instrument used to indicate
the level of the fuel contained in the tank.

7. Future Enhancements
 The accurate distance to zero can also be done
by programming the microcontroller by taking the
input of present mileage with respective speeds
and tank levels.
 In case of theft of vehicle, it can stopped i.e the
engine can be shut down remotely using
additional software enhancements.
