Develop a suitable method to handle parking problem in the crowded big city, as per the demand and number of parking slots available, by giving priority to the users with help of smart parking system. This study proposed Internet of Things-(IoT) based smart parking model using the Arduino UNO model in implementation. This proposed model helps users to allocate booking users vehicles parking free available slot as per time to time availability in college campuses during technical fest in different parking slots and locations. In this working model, Passive Infrared, with ultrasonic Sensors are used which helps to deducting the available parking location and allow us to find out for giving priority based First Come First Serve based-(FCFS) scheduling of parking allotments as per slot is vacant count. This model examine the way of the proposed system with utilizing scenarios of various possible ways with FCFS which show the significance of the parking model using IoT platform. The parking availability detection is capable to find solutions for an empty vehicle parking area for monitoring and reduces users search time as per an automated smart parking model using the internet of things, sensing devices and Arduino UNO(“Uno” means one in Italian languages) in giving priority to users with scheduling model is actual findings with Smart systems. This study proposed an automated parking system to function on a real-time basis to detect all empty parking places based on the internet of things platform, with help of sensors. Arduino UNO platform brings automation to this system on per priority basis to all the users with scheduling techniques. The priority given to users with an automation system is a novelty compared with an existing system. This smart parking is working on real-time basis inputs based on that user demands priority is varying to book parking slots with first come first serve preference.
