Abstract:
Traffic accidents caused by driving under the influence of alcohol and drowsiness have
become pressing issues in our country. This abstract presents an innovative solution that
addresses these concerns by utilizing advanced monitoring and control technologies to
mitigate the risks associated with intoxicated and sleepy drivers. The proposed system
integrates an Arduino Uno microcontroller with an OV7670 camera module to provide
real-time monitoring of driver behaviour. A camera sensor is strategically positioned on
the front windshield to continuously observe the driver’s eye blinking patterns, while
an MQ3 alcohol sensor is securely mounted on the steering wheel to detect alcohol
levels from the driver’s breath. The novelty of this work lies in the integration of
real-time monitoring of both alcohol levels and driver behaviour. Upon starting the
vehicle, the system swiftly measures the driver’s breath for signs of intoxication using the
alcohol sensor. If an unsafe alcohol concentration is detected, the system automatically
disables the ignition, preventing the driver from operating the vehicle. Simultaneously,
the camera continuously analyses the driver’s eye blink rate, identifying prolonged eye
closures indicative of drowsiness. In such instances, the system takes control of the
vehicle, initiating a visual and audible warning to alert the driver and prevent potential
accidents. In the event of a driver blinking their eyes while driving, the system promptly
responds by decelerating the vehicle, bringing it to a controlled stop, and sounding an
alarm to capture the driver’s attention. The alcohol sensor remains active during driving,
automatically reducing speed, bringing the vehicle to a complete stop, and activating
an alarm upon detecting alcohol consumption. By integrating these monitoring and
control mechanisms, the solution aims to significantly reduce accidents caused by alcohol
impairment and drowsiness, representing a promising step towards safer roadways, while
reducing reliance on manual enforcement.
