IOT Based Car Parking System

Car-parking shortages in urban areas create significant congestion, fuel waste, and inconvenience for drivers searching for available spaces. To address these growing challenges, this paper proposes an Iot-based smart parking system designed for large parking lots, aimed at optimizing parking management and improving user experience. The system provides real-time information on the nearest available parking slot, helping drivers quickly locates a free space and reducing traffic caused by parking searches. The proposed design integrates an Arduino microcontroller, infrared (IR) detectors, a servo motor, and a 16×2 I2C display. The Arduino functions t the central controller, managing sensor data and operating the entry and exit mechanisms. IR sensors are used To detect vehicle movement at the gates and determine slot occupancy within the parking lot. A servo motor controls the automated opening and closing of entry and exit gates based on sensor input. At the parking lot entrances, the I2C display shows the number of available slots, enabling drivers to make informed decision before entering. By combining Iot technology with real-time monitoring, this system reduces congestion, saves time, and enhances parking efficiency, offering a practical and scalable solution for modern urban environments.
