Multi-Level Smart Parking System

Internet of things (IOT) allows for numerous opportunities and virtual connections through various devices and objects that digital marketers can take advantage of. IOT involves object interaction by controlling and decontrolling through remote access of devices, vehicles and other articles embedded with electronics, sensors and network connectivity. Since the problem of parking an auto-mobile has been a growing one with the urbanization of societies especially in multi level complexes, in this paper we propose an automated system based on IOT that assigns a parking lot in multiple level parking structure. IR sensors detect changes within the lot and help maintain a database of lots where we can easily identify free and parked lots. This is done be dividing a parking lot into multiple sectors and maintaining an array of Arduino's to monitor them and interface them with a Raspberry Pi so that changes can be pushed into the database through the network module. The system assigns a spot to a customer in an efficient manner prior to entry into the complex by dynamically monitoring and update its state according to the changes internally. The spot is assigned wherein the distance to be covered is minimum while the overall traffic in each level of the complex is regulated in an efficient manner. Suitable verification systems have been implemented to ensure that a pre-assigned spot has actually been occupied.
