SMART CAR PARKING SYSTEM

With the continuous growth of population and rapid urbanization, the number of vehicles on the roads has increased sharply, which has created serious parking difficulties in most cities. Finding an empty parking space has become a frustrating and time-consuming task, especially in busy commercial areas and crowded urban zones. As a result, drivers often keep roaming around in search of parking, which leads to unnecessary vehicle movement, traffic congestion, fuel wastage, and higher levels of air pollution. To overcome these challenges, modern technology is now being used to design smart parking systems that can automatically monitor and manage parking spaces more efficiently. The proposed system is a Smart Car Parking System using Arduino and Sensors, developed to provide a simple, intelligent, and automated way of handling parking slots. It uses an Arduino UNO as the main controller along with Infrared (IR) sensors, a servo motor, and a 16×4 LCD display. The IR sensors detect the entry and exit of vehicles and send this information to Arduino. Based on this data, the servo motor automatically opens or closes the gate. At the same time, the LCD display shows the real-time availability of parking slots, helping drivers immediately known whether a spot is free. This system reduces manual effort, saves time, and prevents unnecessary fuel consumption caused by searching for parking. It also helps reduce pollution and improves the overall efficiency of parking areas. Because it is low-cost, reliable, and easy to implement, this smart parking system is a practical solution that supports the development of cleaner and smarter cities in the future.
