Internet of Things based Car Parking System using ESP- 32 and Blynk

Abstract

The security of the vehicles at the populated places has always been an area of concern. At many crowded places where a number of vehicles enter and exit every day, the security has to be taken into account so that chaos is reduced by using an efficient model. This paper shows the implementation of an Internet of Things based car parking system which consists of electronic components such as infrared (IR) sensors, radio frequency identification (RFID) sensors and servo motors. These are operated using the ESP-32 Dev-Kit V1 DOIT microcontroller board. The Blynk legacy IoT application is used to create a dashboard where the car owner can know the availability of slots and book the slot of his own choice using the Google Assistant from his/her mobile. This helps to avoid the crowd inside the parking lots. It is important to maintain the record of each car and therefore using Internet of Things (IoT) the details of a particular car, with its respective entry and exit time on a particular day are updated into a Google Sheet. In this project, three slots are installed and the overall cost is 1150 INR.
