Simple smart helmet using the RF Module

Smart Helmet using Arduino 🚀

A safety-focused Smart Helmet system that integrates multiple sensors and modules using Arduino to enhance rider security and accident response.

🧠 Key Features

• 🪖 Helmet Detection – Uses an IR sensor to verify if the helmet is being worn.
• 🍺 Alcohol Detection – MQ3 sensor checks for alcohol presence near the mouth region.
• 💥 Accident Detection – Vibration sensor detects sudden impacts/crashes.
• 🚦 Ignition Control – Bike ignition system controlled through safety checks.
• 📱 Emergency Alert System – Sends SMS to emergency contact using GSM module upon accident detection.

🛠️ Hardware Components

• Arduino UNO
• MQ3 Alcohol Sensor
• IR Sensor
• Vibration Sensor
• GSM Module (SIM800L/SIM900A)
• Relay Module
• Battery & Buzzer
• Connecting Wires, Helmet

💡 How It Works

1. Helmet Status Check: The IR sensor inside the helmet detects whether it is worn.
2. Alcohol Check: MQ3 detects alcohol vapor from breath.
3. Start Authorization: Only if both checks pass, the relay turns ON, allowing the bike to start.
4. Crash Detection: Vibration sensor identifies abrupt impacts.
5. Emergency Alert: GSM module sends an SMS to a preset contact with an accident alert.

🚀 Getting Started

2. Connect hardware as per the circuit diagram.
3. Upload the Arduino sketch using the Arduino IDE.
4. Insert a SIM card in the GSM module.
5. Power the circuit and test the functionality.

🧠 Future Improvements

• Add a GPS module for real-time location tracking
• Integrate IoT (e.g., Blynk or Firebase) for live status monitoring
• Add a voice feedback module or an LCD for alerts
