🚗 Automobile Black Box

A Smart Tracking & Data Logging System for Vehicles

🔍 Introduction

The Automobile Black Box functions similarly to an aircraft black box, designed to track, log, and report vehicle-related data, including:

• GPS Location
• Speed Monitoring
• Fuel Logging
• Real-time SMS Alerts
• Accident Analysis & Anti-Theft Measures

It provides insights into driving behavior and helps law enforcement, employers, and individuals track vehicle conditions.
