This project is developed as part of the IEEE Internal Hackathon to address road safety using a Smart Helmet system. The goal is to prevent accidents and enable real-time alerts using affordable embedded tech and mobile connectivity.
The Smart Helmet ensures rider safety through:
- Helmet detection (prevents ignition if helmet is not worn)
- Alcohol detection (blocks ignition if rider is intoxicated)
- Crash detection using motion sensors
- GPS tracking and SMS alerts in case of an accident
| Component | Purpose |
|---|---|
| ESP32 | Main controller (Wi-Fi/BLE) |
| MQ3 Sensor | Alcohol level detection |
| PIR Sensor | Helmet detection via motion |
| MPU6050 | Crash/impact detection (accelerometer) |
| Relay Module | Ignition simulation (ON/OFF) |
| Buzzer | Crash alert |
| Android Phone | GPS + SMS using custom app |
- If helmet not worn or alcohol detected, ignition is blocked via relay.
- If a crash is detected based on total acceleration, a signal is sent.
- Fetches real-time GPS location
- Sends emergency SMS with Google Maps link
- Future scope: BLE trigger from ESP32 on crash detection
The project is fully simulated using Wokwi:
Simulated Features:
- Alcohol level via analog slider (MQ2)
- Helmet detection via PIR
- Crash via MPU6050 drag
- Buzzer + Relay actions
- Serial monitor shows logic flow
- Written in Arduino (PlatformIO or Arduino IDE)
- Clone the repo:
git clone https://github.com/Alpha-5002/RiderSafe
Install dependencies:
- Adafruit MPU6050
- Adafruit Unified Sensor
Upload the sketch to ESP32
- Built using Android Studio in Kotlin
- Requires location and SMS permissions
- Launch app → Tap “Get Location” → Tap “Send SMS”
- BLE-based trigger from helmet to phone
- Fall detection + video recording
- Firebase logging of incidents
- Integration with insurance databases or emergency systems
