IoT Based Smart Parking Platform

Abstract

Parking space is becoming a serious problem due to increasing number of vehicles along with the mismanagement of available parking space. Particularly, in places where sports or artistic events are scheduled, searching for parking space is a major problem. In order to combat this problem, Smart Parking Platform is implemented using sensors to detect when a car enters or leaves a parking lot in order to track capacity and alert drivers about availability of parking space. Inefficient management of parking system effects traffic flow and also leads to wastage of time and fuel. Smart Parking Platform smoothens the parking experience and achieves convenience for users by displaying the status of the parking slots in web browser and guiding drivers towards empty parking slot. In this paper, each parking slot is equipped with an ultrasonic sensor which is interfaced to Arduino UNO microcontroller. Arduino UNO sends the trigger pulse to the ultrasonic sensor. Ultrasonic sensors senses whether the parking slot is empty or occupied and sends the data from echo pin to Arduino UNO, which is programmed in such a way that it processes the data and communicates to Node MCU. The status of the parking spaces is updated in the webpage regularly. The user can access the information regarding parking slots by connecting to the provided network. If a parking slot is empty, it is represented by green block. If it is filled, it is represented by red block. This project aims towards reducing traffic congestion and time while searching for parking space. It can be applicable in places such as convention centers, shopping malls, airports, bus stations, stadiums and theatres.
