PURPOSE: A digital fuel displaying device is provided to compute and digitalize the information for temperature, the amount of fuel, the voltage of a battery, and the injected amount of fuel with a microprocessor and to exactly inform the amount of fuel by being easily separated and attached to a vehicle. CONSTITUTION: A digital fuel displaying device is composed of a senor unit detecting temperature, the amount of fuel, and the voltage of a battery, a sensor interface unit(100) A/D(Analog/Digital)-converting and outputting signals applied from the sensor unit, a microprocessor(130) signal-processing signals applied from the sensor interface, computing the compensation amount of the fuel amount according to the variation of the temperature and the voltage of the battery, and outputting control signals to display signals from the sensor interface, and a display unit(140) displaying data applied from the microprocessor.
