Smart FuelGuard: RFID-Based Protection Against Wrong Fueling

The proposed system is designed to prevent the misidentification of fuel types during the refueling process, ensuring that only the correct fuel type is dispensed into vehicles. This helps to avert potentially severe damage to engines and avoid costly repairs associated with incorrect fueling. The system operates under the control of an Arduino and leverages RFID technology to distinguish between petrol and diesel vehicles. Each vehicle is equipped with an RFID tag specific to its fuel type and positioned near the fuel tank. When a fuel station attendant approaches with the nozzle, an RFID reader embedded in the nozzle scans the tag. If the scanned tag matches the fuel type of the nozzle, the system authorizes the fuel pump to begin dispensing fuel. However, if there is a mismatch, the system immediately activates an alarm, plays a voice alert to notify the attendant, and displays a warning message on an LCD display. This proactive approach significantly enhances safety, minimizes human error, and ensures proper fuel dispensing, providing a robust solution to a common issue at fuel stations.
