Driver Anti-Sleep Alert System Using ATmega328 and Eye Blink Sensor – Smart Automotive Safety Project Kit

Description

🧠 Project Overview

The Smart Driver Anti-Sleep Alert System is a life-saving innovation designed to prevent accidents caused by driver drowsiness or fatigue.
The system continuously monitors the driver’s eye blink pattern using an infrared-based eye blink sensor mounted on smart eyewear.
If the driver’s eyes remain closed beyond a set threshold (indicating drowsiness), the ATmega328 controller immediately activates a buzzer alarm, waking the driver instantly.

This system is compact, rechargeable, and energy-efficient, making it a practical demonstration of real-world automotive safety systems used in modern vehicles.

⚙️ Working Principle

1. Eye Blink Detection:

   • The IR eye blink sensor emits and receives infrared light to detect eyelid movements.

   • When the driver blinks normally, the sensor output stays within a defined voltage range.

   • If the eyes remain closed for too long, the signal indicates drowsiness.

2. Microcontroller Processing:

   • The ATmega328 IC receives sensor input and measures the blink interval using ADC or digital signal timing.

   • If the interval exceeds the safe limit, it triggers an output signal to the buzzer.

3. Alert System:

   • A buzzer produces an audible alarm to alert or wake the driver.

   • Optionally, LEDs or a vibration motor can be added for stronger feedback.

4. Power Supply:

   • The system is powered by a 18650 Li-ion battery, regulated by a USB-C buck-boost converter that maintains stable output even during charge/discharge cycles.

This design ensures portability and long runtime, ideal for real driving environments and academic prototypes.
