Smart Fuelguard: RFID-Based Wrong Fuel Prevention System
The Smart Fuel Guard system is an innovative solution designed to prevent wrong fueling in vehicles using RFID technology and embedded systems. Wrong fueling, such as filling petrol in diesel vehicles or vice versa, can lead to severe engine damage and financial loss. This paper addresses the problem by implementing an automated verification system that ensures the correct type of fuel is dispensed. The system uses an RFID reader mounted on the fuel gun and RFID tags attached to vehicle inlets to identify the fuel type before dispensing. The core of the system is the Arduino Uno microcontroller, which processes the data received from the RFID reader using SPI communication. The system compares the unique identification number (UID) of the RFID tag with predefined values stored in the program. Based on this comparison, the system determines whether the fuel type matches the vehicle requirement. The output is then communicated to the user through a 16x2 LCD display using I2C protocol, along with visual indicators using green and red LEDs and an audio alert using a buzzer. Overall, the Smart Fuel Guard system provides a reliable, cost-effective, and efficient solution to prevent wrong fueling at fuel stations. It enhances safety, reduces human errors, and improves customer satisfaction by ensuring accurate fuel dispensing. This paper also highlightsthe practical application of embedded systems and RFID technology in solving real-world problems and has potential for further improvements and large-scale implementation
