Abstract: The Smart FuelGuard system will be created to ensure safe, automated, and error-free fuel dispensing through a combination of RFID authentication, PIN verification, and sensor-based fuel monitoring. All the parts are connected to an Arduino microcontroller as the primary control unit. The RFID reader checks with users, and a keypad enables entry via PIN and the amount of fuel to use. An I2C LCD displays the status, instructions, and error messages of the system. A relay module powers the DC pump to imitate fuel dispensing, and a buzzer has been used to give feedback on unauthorized cards, wrong PIN inputs, or any problems within the system. A controlled power supply will make all modules operate consistently. It also has a color sensor to identify the type of fuel using the optical properties; it is used to check whether the fuel dispensed is of the correct type as assigned, and determines whether there is a mismatch or abnormal color, and the pump is automatically switched off, and an alarm is activated to avoid misfueling. With legitimate authentication, PIN check, and a kind of fuel check, the Arduino will switch on the pump and run it for a predetermined time period according to the amount of fuel chosen. The prototype has a proven, intelligent, and simple fueling system that can boost the safety and eliminate expensive engine damage caused by improper fueling.
