This project tackles common problems in traditional parking systems, such as long search times, manual processes, and inefficiencies, especially in busy areas. To address these issues, we developed a smart parking system that uses QR code technology to automate and secure vehicle entry and exit. The system features a website application that lets users register, view available parking spots in real time, and manage access without needing to download any mobile apps. The smart parking system improves parking management by allowing real-time tracking of slots, reducing the need for human involvement, and enhancing traffic flow. It decreases congestion at entry and exit points through automation, which significantly cuts down waiting times. Users enjoy a convenient, contactless experience, while operators benefit from better use of slots, lower operational costs, and reliable data for planning and assessment. Key hardware components include ESP8266 and ESP32-CAM microcontrollers, IR sensors, a display, a servo motor, LED indicators, and a buzzer, all linked through a local Wi-Fi network. Users register on the website, scan a QR code at the entrance using their phone browser, and receive a parking slot. After payment is completed, a unique QR code is generated for exiting the parking area. Testing showed that the system achieved 100% reliability in all main functions, proving its efficiency and ease of use. The solution is low-cost, scalable, and user-friendly, making it appropriate for real-world settings like campuses, malls, and public parking facilities. In conclusion, this smart parking system offers a practical and effective way to modernize parking management, with strong potential for future improvements, such as integrating payment gateways and mobile applications.
