Smart Misfuel Detection System

Overview

The Smart Misfuel Detection System is designed to prevent misfueling incidents by identifying fuel types (Diesel or Petrol) using a TCS3200 color sensor. The system incorporates real-time monitoring, error detection, and automated alerts to ensure operational efficiency and safety in fuel stations or similar environments.

Features

• Accurate Fuel Detection: Identifies Diesel and Petrol based on pre-calibrated sensor thresholds.
• Misfuel Prevention: Alerts users with a buzzer if the detected fuel type mismatches.
• Automated Alerts:
  • Plays a warning buzzer if Diesel is detected.
  • Issues an error notification if the system is left open for more than 1 minute.
• Energy-Efficient Operation: Automatically powers down the sensor when idle.
• Real-Time Monitoring: Outputs sensor readings via Serial Monitor for live debugging and analytics.
• Relay Integration: Controls external devices like pumps based on the detected fuel type.

Components Used

1. TCS3200 Color Sensor: Detects the color properties of the fuel.
2. Arduino (Microcontroller): Processes data and controls the connected components.
3. Magnetic Door Sensor: Detects when the system is opened or closed.
4. Relay Module: Activates external devices based on the fuel type.
5. Buzzers: Alerts users in case of misfueling or errors.
6. LED Indicators (Optional): Provides visual feedback for system status.

How It Works

1. The system activates the TCS3200 sensor when the door is opened.
2. Reads Red, Green, and Blue pulse width values from the fuel.
3. Determines the fuel type using pre-set thresholds.
4. Actions:
   • Diesel Detected: Activates the relay and sounds a buzzer.
   • Petrol Detected: Keeps the relay inactive, no buzzer sound.
   • No Fuel Detected: Outputs an error message and turns off the relay.
5. Plays a warning tune if the door remains open for 1 minute.

Setup Instructions

1. Assemble the components as described in the setup() function.
2. Upload the code to the Arduino using the Arduino IDE.
3. Use the Serial Monitor (baud rate: 9600) to view real-time sensor readings.
4. Adjust the color thresholds in the detectFuelType() function if required.

Code Explanation

• Initialization:
  • Pins, sensors, and communication are configured in setup().
• Core Logic:
  • The loop() continuously monitors the door state, reads color values, and determines the fuel type.
• Functions:
  • getRedPW(), getGreenPW(), getBluePW() measure the color pulse widths.
  • detectFuelType() identifies the fuel type and activates relevant components.
  • playErrorTune() sounds a warning buzzer if the door is open too long.
• Customization:
  • Change the time interval for the warning in errorBeepInterval.

Applications

• Fuel Stations: Prevents misfueling incidents automatically.
• Industrial Automation: Detects and categorizes liquids in production lines.
• Smart Monitoring Systems: Provides real-time analytics and error alerts.

Future Enhancements

• Add a digital display for visual feedback of fuel type.
• Integrate IoT features for remote monitoring and control.
• Expand the system to detect additional fuel or liquid types.
• Enable data logging for analytics.
