How It Works

The iN-Car Drowsiness Detection and Alert System operates by continuously monitoring the driver's facial features and eye status using an advanced AI vision module. The setup utilizes a Logitech C270 camera module paired with a Sipeed Maixduino development kit to run an edge-AI eye detection algorithm in real time. When the vision system detects prolonged eye closure or signs of fatigue, it signals the ESP32-WROOM-32 microcontroller to take action. The ESP32 processes this alert state and interfaces with the vehicle's internal network via an MCP2515 CAN Bus module, allowing the system to communicate critical safety messages or vehicle-state data. Simultaneously, local hardware alerts are triggered through a connected buzzer and 5mm LEDs. The entire hardware circuit is powered reliably using a dedicated voltage regulator and power module, supplemented by passive components such as resistors, capacitors, and diodes to ensure stable electrical operation and signal filtering within the automotive environment.

Frequently Asked Questions

Can I use any standard webcam instead of the Logitech C270?

The vision algorithm and processing boards are typically optimized for specific USB or compatible camera modules like the C270 to ensure reliable frame rates and low-latency eye detection.

Why are both an ESP32 and a Sipeed Maixduino used in the same project?

The Maixduino handles the intensive edge-AI computer vision tasks required for real-time eye tracking, while the ESP32 manages general system control, local alerts, and CAN bus communication.

How does the MCP2515 module connect to the vehicle?

The MCP2515 module acts as a CAN controller that interfaces the ESP32 via SPI to the physical CAN transceiver, allowing connection to the vehicle's CAN-High and CAN-Low data lines.
