Use Cases of the System
| Use Case | Description |
|---|---|
| Sign Up | New users register to start using the application. |
| Sign In | Post-registration, users access the application's features. |
| Accident Location | Displays accident location on the app's map interface. |

Hardware Description
The NodeMCU ESP32, operating over Wi-Fi, initiates connections to the controller. The GPS sensor starts searching for satellites to determine the incident location once connected. The alert mechanism is entirely self-contained within the device, requiring no external applications.
When the ultrasonic sensor detects close proximity to an obstacle, it activates the buzzer to alert the driver. The alert can be disabled by either increasing the distance from the obstacle or manually turning it off. The GPS sensor provides location data, but the critical component is the 3-axis accelerometer. This sensor continuously monitors XYZ axis values, with thresholds set based on UTM road data. The system sends location data to the application via push notification, allowing users to view the incident location.
Software Description
The Android mobile application displays incident locations on a map. Notifications serve as the first point of contact, alerting users before showing location details. The process begins on the app's homepage. Upon receiving a notification, the app displays the coordinates of the incident location. When users click on the notification, the app shows detailed accident location information along with a map pointer.
Conclusion
The "Save Me: Accident Alert & Notification System" is a comprehensive solution designed to reduce traffic fatalities through prompt alerts and precise location tracking. By integrating advanced hardware and software technologies, the system ensures timely emergency responses and enhances road safety.
