DIGITAL FUEL LEVEL INDICATOR AND RESERVE ALARM
Abstract : In this project the tank consists of a level sensor which is special type of sensor in which the resistance value is varied depending upon the fuel level. The variable resistance obtained from the level sensor is given into the amplifier in order to amplify the signal. Then the amplified voltage signal is given to ADC. ADC is nothing but Analog to Digital Converter which converts the analog signal from the level sensor to corresponding digital signal. Then the converted digital signal is given to microcontroller. Here the microcontroller is the flash type reprogrammable microcontroller in which we have already programmed. Now the microcontroller displays the corresponding fuel level on the LCD display. The fuel level of the tank decreases below reserve level, the microcontroller gives the pulse to driver circuit. The driver circuit is used for provide the sufficient input voltage of alarm. The alarm will produces sound to indicate the reserve level in the fuel tank.
? Accuracy may vary while driving through hill stations.
? Low power consumption.
? It is used to monitor the fuel level in the tank.
? Simple and efficient.
? Less expensive.
? Accuracy is high
