Fuel Level Monitor with 15 Segments Bar-Graph Display
This Fuel level Monitor allows users to measure the fuel level using a resistive float sensor in the fuel tank. The project measures the fuel level and displays it on a 15-segment bar-graph display. The project is Arduino-compatible and consists of ATMEGA328 controller. The resistive sensor with a divider resistor is connected to Analog pin A0 of the MCU chip. The 15 LEDs of different colors are connected to various Arduino pins.
Sensor
A resistive sensor is used to measure the fuel level. This sensor with 1kΩ divider resistor outputs analog values 785 to 984. This analog signal is connected to ADC A0 of the Arduino chip. Arduino chip evaluates input signal and controls 15LEDs. Different sensor provides different outputs. It is advisable to map the right value in Arduino code as per the sensor’s output.
