Automatic crash detector sensor in cars

1. Objective: Detect car accidents automatically and send emergency alerts.

2. Components: Arduino/ESP32, accelerometer (MPU6050), GPS module, GSM module, power supply, buzzer, LEDs.

3. Working Principle: Detect sudden acceleration or impact using the sensor.

4. Detection: When acceleration crosses a threshold → crash detected.

5. Process:

Measure acceleration continuously.

If crash occurs → get GPS location.

Send SMS alert via GSM to emergency contacts.

1. Alert Message: Includes accident alert + location coordinates.

2. Power Backup: Small battery to send alert even if car power fails.

3. Output Indicators: LED or buzzer to confirm system and alert status.

4. Testing: Simulate impact to verify alert transmission.

5. Future Upgrade: Add camera recording, AI detection, or IoT cloud link.tion
