Detailed Working of IoT-Based Smart Car Parking System with Real-Time Online Booking :

The IoT-Based Smart Car Parking System with Real-Time Online Booking is a sophisticated and innovative solution designed to streamline the parking process in urban settings. This system integrates several components that work harmoniously to ensure real-time monitoring and management of parking spaces, making it convenient for users to book parking spots online. The circuit diagram is central to understanding the complete operation of this system.

The heart of our circuit is the microcontroller, typically an ESP8266 or ESP32, which is responsible for handling communication between various sensors and the online platform. The circuit is powered by a 5V power supply, and the microcontroller's pins are connected to multiple sensors and actuators that perform various functions. The first set of components connected to the microcontroller are the ultrasonic sensors, which are placed at each parking slot. These sensors continuously monitor the availability of the parking slots by sending sound waves and measuring the distance to the nearest object. When a car occupies a slot, the distance measured by the sensor is shorter, indicating the slot is occupied. This data is sent to the microcontroller for processing.

Additionally, the system includes an LCD display mounted at the entrance of the parking lot, which provides real-time updates on the availability of parking spaces. The microcontroller processes the data from the ultrasonic sensors and updates the LCD display accordingly. For instance, it shows the number of available and occupied slots, thus giving drivers instant information as they approach the parking facility. To enhance user interaction, pushing the data online is an integral feature of the system. Real-time data about the parking slots is sent to a cloud server via Wi-Fi, allowing users to check slot availability and book spaces remotely using their smartphones or other devices.

An essential part of the circuit is the servo motors, which control the entry and exit gates. The microcontroller communicates with these motors to manage the opening and closing of the gates based on the data from the booking system and the sensors. When a user books a slot online, a signal is sent to the microcontroller to open the entry gate. As the car passes through the entry sensor, the gate closes automatically after a brief delay. Similarly, the exit gate operates based on signals from the exit sensors, ensuring a smooth flow of vehicles in and out of the parking lot.

The buzzer and LED indicators connected to the microcontroller serve as alerts for various statuses and actions. For instance, if an unauthorized vehicle tries to enter or if there's an error in the booking process, the buzzer sounds to alert the facility manager. Moreover, the LEDs indicate the status of the parking slots – green for available and red for occupied.

Hence, the IoT-Based Smart Car Parking System with Real-Time Online Booking circuit functions efficiently to create a seamless parking experience. The microcontroller acts as the central hub, processing data from various sensors and facilitating communication with the online platform. Through this interconnected system, real-time management of parking slots is achieved, making it easier for users to find and book parking spaces conveniently. This advanced technology not only saves time and effort for drivers but also optimizes the use of parking facilities, leading to better urban traffic management.

Modules used to make IoT-Based Smart Car Parking System with Real-Time Online Booking :

1. Power Supply Module

The power supply module is a crucial part of the IoT-based smart car parking system. This module is responsible for converting and providing the necessary electrical power needed to operate all components of the system from a standard 230V AC wall outlet. The AC current is first stepped down via a transformer to a lower AC voltage. This low voltage AC current is then rectified by a bridge rectifier to convert it into DC. To smooth out the ripples and obtain a stable DC output, capacitors are used. Finally, voltage regulators are employed to ensure a constant DC output voltage suitable for the microcontroller and other electronic components. Proper powering ensures the reliable operation of sensors, motors, microcontroller, and display modules.

2. Microcontroller Module

The microcontroller module serves as the brain of the system, governing all operations based on inputs from various sensors and executing the necessary output commands. In this project, an ESP8266 module is used, which provides integrated Wi-Fi capabilities essential for IoT connectivity. The microcontroller receives sensor data from ultrasonic sensors positioned to detect car presence and sends the status of parking slots to a central server in real time. It also controls the motors for the entry and exit gates and interfaces with the LCD display to show the availability status of parking slots. Through a Wi-Fi network, the microcontroller connects with a cloud service to facilitate online booking and processing of parking data remotely.

3. Sensor Module

The sensor module is crucial for detecting the presence of vehicles within parking slots. This system uses ultrasonic sensors, which emit ultrasonic waves and measure the reflection to determine the distance to the nearest obstacle. Each parking slot is equipped with an ultrasonic sensor that constantly monitors the slot. When a car is parked, the sensor detects the shorter distance and sends this data to the microcontroller. The microcontroller processes this information to update the status of the slots, whether occupied or vacant, and transmits this data to the central server and updates the local display accordingly. This real-time data transmission maintains accurate status for online booking users.

4. Motor Module

The motor module consists of servo motors used to control the entry and exit gates of the parking system. These motors receive control signals from the microcontroller to open or close the barriers. When the microcontroller gets a signal indicating that a car is approaching the entry gate and there are available slots, it sends a command to the servo motor to open the gate, allowing the car to enter. Similarly, when a car approaches the exit gate, the microcontroller commands the corresponding servo motor to lift the exit barrier, letting the car out. The precise movement control of the motors is essential for efficient and secure operation of the gates.

5. Display and Alert Module

The display and alert module, consisting of an LCD display and a buzzer, provides real-time status information and alerts to users. The LCD display is connected to the microcontroller and shows the number of available parking slots. This display is typically installed at the entrance to inform drivers about slot availability before they enter the parking area. The buzzer, also controlled by the microcontroller, can be used to emit sound alerts for various events, such as when a car parks or when unauthorized entry is detected. This module enhances user experience by providing clear visual information and audible alerts for prompt action.

6. Connectivity and Data Transmission Module

The connectivity and data transmission module is pivotal for integrating the parking system with IoT and enabling real-time online booking. The ESP8266 microcontroller’s built-in Wi-Fi capability is utilized to connect to the internet and communicate with a cloud server. The system sends data from the sensors regarding the occupancy status of parking slots to the server. Users can book parking slots online via a mobile app or web interface, which accesses this real-time data from the server. The server processes bookings and transmits commands back to the microcontroller for control actions such as updating the display or operating the entry gate, thus ensuring seamless integration and automation.
