The Arduino setup includes the crash sensor, which detects sudden impacts or collisions. When triggered, the Arduino sends a signal via Bluetooth to the paired Android device. The Android app receives this signal, prompting it to capture the device’s current location using its built-in sensors.

The Android app then displays this location on a map interface, allowing users to visualize the vehicle’s position in real-time. Additionally, the app can notify designated contacts or emergency services about the accident, providing crucial information for swift response and assistance.
