Abstract - Today, parking has become a major problem due
to the rising usage of cars everywhere. We are introducing an Internet of Things (IoT)-enabled parking system that allows users to view and book parking spaces. For security purposes, we have an RFID reader placed at the entry gate. Making it easier for consumers to determine whether parking spots are available at an excessive parking area prior to coming is the primary goal of this project. All parking system issues are significantly reduced as a result of the more clever and efficient parking mechanism that is produced. Every slot has a sensor that continuously checks its condition and updates the data to the cloud platform and application, which allows users to verify parking availability and reserve a spot.
Servo Motor
regulates the opening and closing of a parking gate or barrier.
LCD (16x2)
shows the parking status (e.g., "Slot Full" or "Slot Available").
Jumper Wires utilized for all electrical connections. Cell Holder
attaches the 3.7V cell to the circuit and holds it firmly.

Key words: IoT, sensors, cloud platform, smart parking, secured parking, etc. 1.INTRODUCTION The Internet of Things (IoT) uses the internet to link different physical items and devices worldwide. The Internet of Things (IoT) is a system that links computers, machines, etc. that have been assigned unique identities (UIDs). It allows data to be sent across a network without the need for communication between the objects [1-4]. IoT is essentially an extension of Internet-based services [5-8]. In order to collect and share data over a network without requiring human-to-human or human-to-computer interaction, the Internet of Things (IoT) is a network of physical objects, such as instruments, devices, and other items embedded with electronics, circuits, software, sensors, and network connectivity [9–11]. The Internet of Things makes it possible to remotely sense and control objects over an existing network infrastructure. also creating opportunities for more direct integration of the physical world into computer-based systems, and leading to improved efficiency and accuracy Component

Fig.1: Proposed system block diagram To determine whether there are cars in parking spaces, the ESP8266 NodeMCU, the primary controller of the Internet of Things-based smart parking system, gets data from IR sensors (IR1, IR2, and IR3). The ESP8266 uses sensor input to control a servo motor that opens or closes the entry gate and shows the parking status in real time on an LCD. Additionally, it transmits real-time parking data to the Blynk IoT Cloud, enabling users to Use a smartphone to verify the slots' availability remotely. The entire system is powered by a dedicated power source.
Detects the presence of a vehicle (entrance or exit).
