The aim of our project is to monitor the level of the fuel in the vehicle fuel tank and to automatically indicate the level information through LCD display
In our project the main blocks are micro controller unit, fuel level sensor and LCD display unit. The fuel level detection circuit is used to detect the level of the fuel in the tank; here sensors are placed at certain places to find out the fuel level and the signals are sent to the micro controller unit for further operations.
Here sensors are placed at various places to sense the fuel level and the signals from these sensors are sent to the micro controller unit to decide the exact level information. When the fuel level reaches the top level sensor which means that the tank is full and this will be indicated to the user by means of beep noise and the level information is indicated through LCD.
Here the level information are displayed in terms of percentage and these information are preprogrammed according to the sensor position. The buzzer indication is set to execute once for medium level and for high level and it will repeat continuously for the low level until the user press the key
