Hardware
- LiDAR sensor: measures distance to the tire surface for tread depth estimation
- Raspberry Pi 5: runs MATLAB processing and handles data collection
- GPS module: provides vehicle speed and location data
- Accelerometer: measures vibration and motion
- Temperature sensor: monitors tire temperature
- I2C controller: enables communication between sensors
Software
- Real-time data acquisition using MATLAB
- LiDAR data parsing and distance extraction
- Noise filtering and signal stabilization
- Tread depth calculation based on distance change
- Tire life estimation
- Data upload to Firebase for visualization
Data Flow
Sensors → Raspberry Pi (MATLAB) → Firebase → Mobile App
- The system collects sensor data, processes it in real time, and uploads the results for remote monitoring and visualization.
