1. Purpose:
Drowsiness Detection: The primary goal is to monitor the driver’s eye status to detect drowsiness or inattention, which can then trigger alerts or vehicle control actions.

2. Components:
Camera: A camera mounted on the dashboard or near the rearview mirror, focused on the driver's face to capture real-time video.
Onboard Computer: An automotive-grade computer (like a sipeed maixduino or dedicated microcontroller) to run the eye detection and status processing algorithms.
CAN Bus Interface: Interface to the vehicle’s CAN (Controller Area Network) bus to communicate with other vehicle systems.
Alert System: Speakers, vibration motors, or visual indicators (e.g., dashboard lights) to alert the driver.
Communication Module: Wi-Fi, GSM, or Bluetooth module for remote data transmission and integration with cloud services or external servers.
Power Supply: Connection to the vehicle’s 12V or 24V electrical system, with appropriate voltage regulation to power the components.

3. Workflow:
Capture and Process Data:

The camera captures the driver’s eye movements in real-time.
The onboard computer processes the video feed using the provided eye detection algorithm to determine the eye aspect ratio (EAR).
