A Helmet with Fall Detection and GPS Alert is a smart safety device designed for motorcyclists, construction workers, miners, and other field workers. The helmet is equipped with fall detection sensors that detect sudden impacts or unusual head movements indicating an accident. Upon detection, the system automatically triggers a GPS module to capture the location and sends an alert via SMS or IoT platform to emergency contacts.

This system helps ensure quick medical response, improving survival chances and reducing injury severity after accidents.

Parts Used:

1. Helmet Shell – standard ISI/BIS certified helmet for protection
2. Accelerometer / Gyroscope Sensor (e.g., MPU6050) – detects fall or impact patterns
3. Microcontroller (Arduino / ESP32) – processes sensor data and controls alert system
4. GPS Module (Neo-6M or similar) – determines exact accident location
5. GSM Module (SIM800L / SIM900) – sends SMS with GPS coordinates to emergency contacts
6. Rechargeable Battery (Li-ion/Li-Po) – powers the electronics
7. Buzzer / LED Indicator – provides local alarm and status indication
8. On/Off Switch – for system activation/deactivation
9. Shock-absorbing Mounts – secure electronics inside helmet without affecting comfort
10. Optional: Bluetooth module for mobile app alerts
