IoT-Enabled Car Parking System with Raspberry Pi Integration via MQTT Protocol

Project Description:

The project focuses on designing and deploying an IoT-enabled car parking system that integrates Raspberry Pi technology and MQTT protocol to provide real-time status updates on mobile applications. By leveraging Raspberry Pi and MQTT, the system aims to enhance parking management and provide drivers with convenient access to parking space availability information.

Key Components:

1. Raspberry Pi Zero 2W: Serve as the core computing units for both sensor nodes and the central control unit.
2. Parking Sensors: Installed at individual parking spaces to detect the presence or absence of vehicles.
3. Mobile Application: Developed to display live status updates on parking space availability to users.
4. MQTT Protocol: Facilitates efficient and reliable communication between Raspberry Pi units and the mobile application.
5. Central Control Unit: Manages data processing and communication between sensor nodes and the mobile application.
6. Sensor Nodes: Deployed at each parking space to collect occupancy data and transmit it to the central control unit.

Project Features:

1. Real-Time Status Updates: Provides users with live updates on parking space availability via the mobile application.
2. Color-Coded Indicators: Visualizes parking space availability on the mobile application using color-coded indicators.
3. Efficient Communication: Utilizes MQTT protocol for seamless and secure communication between Raspberry Pi units and the mobile application.
4. Improved Parking Management: Enhances parking efficiency by enabling drivers to locate available parking spaces more easily.
5. User Convenience: Empowers users to make informed decisions about parking their vehicles based on real-time information provided by the system.

Project Workflow:

1. Sensor Deployment: Install parking sensors at individual parking spaces to detect vehicle presence.
2. Raspberry Pi Integration: Configure Raspberry Pi boards as sensor nodes and a central control unit for data processing and communication.
3. MQTT Setup: Establish MQTT communication protocol between Raspberry Pi units and the mobile application.
4. Mobile Application Development: Design and develop a mobile application to display live parking space status updates to users.
5. Testing and Optimization: Conduct thorough testing of the system to ensure accuracy, reliability, and efficiency in parking space detection and status updates.

Benefits and Applications:

1. Enhanced Parking Efficiency: Improves parking space utilization and reduces the time and effort required to find available parking spaces.
2. User Convenience: Offers drivers real-time information on parking space availability, enhancing user convenience and satisfaction.
3. Optimized Parking Management: Provides parking lot operators with valuable insights into parking space utilization, enabling better management and planning.
4. Scalability and Adaptability: The system can be easily scaled and adapted to various parking environments, making it suitable for both small-scale and large-scale applications.
