Traffic accidents cause many fatalities. Smart helmets combine sensors and communication to detect accidents and notify emergency services.

- Accident Detection (sensors)

- Emergency Alerting (GSM/IoT)

- Helmet Usage Monitoring

- Alcohol Detection (optional)

- Low-cost & Reliable

- Real-time Operation

- Scalability & Data Collection

- Helmet Integration (sensors, GPS, GSM)

- Microcontroller Unit (Arduino, ESP32, STM32)

- Power Source (batteries, regulators)

- Track acceleration & orientation

- Detect abrupt changes & vibrations

- Use algorithms to reduce false alarms

- Activate GPS for location

- Notify emergency contacts via GSM SMS

- Optional IoT cloud monitoring

- Infrared sensor detects helmet wear

- Optional ignition block if not worn

- MQ3 sensor detects alcohol

- Alert & ignition block if threshold exceeded

- Microcontroller coding (Arduino IDE, ESP-IDF)

- Accident detection algorithms

- GSM & GPS data handling
