IoT-Based Smart Parking System Using Arduino Uno & RFID

Introduction

Managing parking efficiently in urban areas is a growing challenge. The IoT-Based Smart Parking System using Arduino Uno & RFID offers an automated, secure, and real-time parking solution. It helps in reducing congestion, preventing unauthorized parking, and providing live updates on parking availability.

Features

• Arduino Uno-Based Control System – The core microcontroller processes RFID data and controls parking access.
• RFID-Based Vehicle Authentication – Allows only authorized vehicles to enter and exit.
• IoT Connectivity – Updates real-time parking slot availability on a cloud dashboard.
• Automated Boom Barrier – Opens and closes based on RFID authentication.
• Ultrasonic Sensors – Detects and updates the number of occupied/free slots.

Working Mechanism

1. Each vehicle is assigned an RFID tag containing a unique identification number.
2. When a vehicle approaches the parking entrance, an RFID reader (connected to the Arduino Uno) scans the tag.
3. If the tag is authenticated, the servo motor-controlled boom barrier opens, allowing entry.
4. Ultrasonic sensors monitor available slots and send data to the IoT platform.
5. When exiting, the RFID tag is scanned again, updating the parking availability.
6. Real-time data is displayed on an LCD screen and a web-based dashboard.

Applications

• Shopping Malls & Offices – Provides efficient parking management.
• Residential Societies – Restricts unauthorized vehicle entry.
• Public Parking Lots – Enhances security and automation.
• Universities & Hospitals – Ensures smooth parking operations.

Benefits

• Reduces congestion with automated parking slot detection.
• Enhances security by allowing only authorized vehicles.
• Minimizes human intervention with an automated system.
• Provides real-time updates via an IoT dashboard.

Conclusion

The IoT-Based Smart Parking System using Arduino Uno & RFID is an innovative approach to automated parking management. It enhances security, efficiency, and convenience, making it ideal for modern parking infrastructures.
