Vehicle Accident SMS Responder with GPS Location

Vehicle Accident SMS Responder with GPS Location Project Report

Introduction

This project describes an Arduino-based system designed to automatically send an SMS alert with GPS location in case of a vehicle accident. This system aims to improve response times for emergencies by notifying predefined contacts and providing a map link for quick access to the accident scene.

Components

• Arduino Uno (or compatible board)
• GPS Module (e.g., Neo-6M)
• GSM Module (e.g., SIM800L)
• LCD Display (optional for real-time feedback)
• Gyroscope Sensor (e.g., MPU6050)
• DC Motor (represents engine)
• Breadboard
• Jumper Wires
• GSM SIM Card with SMS functionality
• External Power Supply (e.g., Li-ion battery)

System Functionality

1. Device Activation: Upon user activation (through a switch or button), the system sends a confirmation SMS (“Connect OK”) to a predefined mobile number.
2. Engine Start Simulation: A DC motor simulates engine start, indicating system readiness.
3. Accident Detection: The gyroscope sensor detects a tilt exceeding a predefined angle, signifying a potential accident.
4. SMS Alert with Location: Upon detecting a tilt, the system triggers an SMS containing a link. Clicking this link opens a Google Maps window displaying the accident location retrieved from the GPS module.
5. Emergency Response: The predefined contact receives the SMS and can access the accident location through the map link, enabling a faster response.

Report Sections

• Hardware Design: Provide a detailed schematic diagram illustrating the connections between Arduino, GPS, GSM module, gyroscope, LCD (if used), and motor. Briefly explain the functionalities of each component.
• Software Development: Explain the Arduino code structure. Include comments within the code to enhance readability. The code should address:

• Library inclusions for GPS, GSM, and (if used) LCD functionalities.
• Variable declarations for storing SMS recipient number, GPS coordinates, and tilt threshold.
• Functions for:

• Initialization of modules (GPS, GSM)
• Reading GPS data (latitude and longitude)
• SMS sending routine with location link generation (using a web mapping service API or pre-defined static map URL with accident coordinates)
• Gyroscope data reading and tilt detection logic
• Engine start simulation control (optional for motor control)

• Testing and Results: Describe the testing procedures performed. This may include simulating different tilt angles and verifying successful SMS transmission with location link functionality. Discuss the obtained results and address any challenges encountered during testing.

Conclusion: Summarize the project’s achievements and potential applications. Briefly discuss limitations and areas for future improvements, such as incorporating additional sensors for more precise accident detection or integrating with emergency response services.

Additional Considerations

• Power Management: Include a power management plan to ensure sufficient and reliable power supply during operation.
• Real-time Feedback (Optional): Utilize the LCD to display real-time data like GPS coordinates, gyroscope readings, and system status messages.
• Accident Severity: Explore incorporating additional sensors (e.g., accelerometer) to differentiate between minor tilts and potentially severe accidents.
• Data Security: Implement security measures (e.g., password protection) for accessing the predefined contact information stored on the Arduino.
