Driver Sleep Detection and Alarm with GPS SMS | Driver Drowsiness Detection

Driver Sleep Detection and Alarm with GPS SMS System

Project Overview

The Driver Sleep Detection and Alarm with GPS SMS System is an intelligent vehicle safety solution designed to detect driver drowsiness in real time and prevent accidents caused by fatigue. The system continuously monitors the driver’s facial features using a camera and image processing techniques. When signs of sleep or drowsiness are detected, an alarm is activated instantly and an SMS alert containing GPS location is sent to a predefined contact.

This project integrates computer vision (Python), embedded systems (Arduino), GPS tracking, and GSM communication, making it highly suitable for modern road safety applications.

Objective of the System

• To detect driver drowsiness accurately

• To alert the driver immediately using sound or vibration

• To send emergency SMS alerts with real-time GPS location

• To reduce accidents caused by fatigue and microsleep

Working Principle

1. A camera continuously captures the driver’s face.

2. A Python-based image processing algorithm analyzes eye blink rate, eye closure duration, and facial landmarks.

3. If prolonged eye closure or drowsy behavior is detected:

   • The system triggers a buzzer/alarm to alert the driver.

4. Simultaneously, the GPS module fetches the vehicle’s real-time location.

5. The GSM module sends an SMS alert with GPS coordinates to a predefined emergency contact.

6. The system continues monitoring until normal driver behavior resumes.
