IoT and RFID Based Car Parking with Wireless Charging

IoT and RFID Based Car Parking with Wireless Charging

Project Overview

The IoT and RFID Based Car Parking with Wireless Charging system is an intelligent parking management solution designed to automate vehicle entry, parking slot allocation, authentication, and wireless charging using modern IoT technologies. The system enhances parking efficiency, security, and user convenience by integrating RFID identification, real-time IoT monitoring, and wireless power transfer.

This project is especially suitable for smart cities, shopping malls, offices, airports, and EV parking zones.

Objective

• To automate car parking using RFID authentication

• To monitor parking slot availability in real time

• To enable wireless charging of vehicles while parked

• To display live parking and charging status using IoT

• To reduce human intervention and improve parking efficiency

System Working Principle

1. RFID Authentication

   • Each vehicle is assigned a unique RFID card.

   • At the entrance, the RFID reader scans the card.

   • Only authorized vehicles are allowed entry.

2. Slot Detection

   • IR sensors detect whether parking slots are empty or occupied.

   • Slot availability is updated in real time.

3. Wireless Charging

   • When a vehicle is parked in a designated slot, wireless charging coils activate.

   • Power is transferred using electromagnetic induction without physical connectors.

4. IoT Monitoring

   • Parking and charging data are sent to an IoT platform.

   • Users and administrators can monitor:

     • Slot status (Free / Occupied)

     • Charging status (ON / OFF)

5. Display & Alerts

   • LCD shows parking messages like:

     • Slot full

     • Charging ON

     • RFID authentication status
