Due to the availability of technology and basic necessities, smart cities are now increasingly populated. In order to inspect, monitor, and signal the availability of parking spaces or slots in crowded regions, we presented a smart parking system that entails the deployment of an IOT module on-site. This project combines IOT with a coordinated framework for an effective and simple method of parking the auto-mobiles without having to look for open spaces. The main intention of this Smart Parking system is to comprise the IOT module which is utilized for signaling the driver of vehicle and mainly its condition of accessibility of single parking spot or place. The project also includes a perspective on the engineering of the framework from an abnormal state. At its conclusion, the project analyses the framework's operation in the form of a usage case that supports the viability of the suggested show. The Arduino Uno and Ultrasonic Range Detection Sensor are used to visually identify the vacant slots. Vehicle drivers can locate the open spot in the parking lot by measuring the distance using ultrasonic sensors. It can reduce the amount of time spent seeking and make it very easy for the driver to find the spot. As soon as a parking space in the parking lot is discovered to be unoccupied, ultrasonic sensors are used to identify it, which results in a further report. Programming the Arduino Uno, sensors, and other components enabled us to accomplish this. The main foremost inspiration of this idea is to minimize the clog of vehicles in urban areas effectively. In the daily newspapers, we have seen many articles with respect to the vehicles stopping issues and parking place issues all over India and mainly in the cities like Delhi, Mumbai, Chennai, Bangalore and numerous metropolitan urban areas. In a recent study, many researchers have found that for one year, the vehicles like cars and bikes are consuming approximately 186823. 5 liters of fuel and releasing almost 825 tons of carbon dioxide. Everyone is responsible for this so, the aimless driving should come to an end in the parking areas where this project is highly suitable to save the nature and parking problems all over the world.
