Smart Door Opener

Description

The Smart Door Opener project is designed to automate door operation using an ESP32 microcontroller combined with a distance sensor. This system provides remote access control functionality, allowing users to open or close their door from anywhere through a web interface.

Technologies Used

Hardware

• ESP32 Microcontroller: Acts as the central controller for the Smart Door Opener system, handling the communication between the distance sensor and the web application.

Software

• C: Programming language used for developing the firmware for the ESP32 microcontroller.
• Node.js: JavaScript runtime used to create the backend server that interfaces with the ESP32.
• Express.js: Web framework for Node.js, used to build RESTful APIs for communication between the backend server and the web interface.
• WebSocket: Protocol used to enable real-time, two-way communication between the server and the web client.
• HTML: Markup language for structuring the web interface.
• CSS: Stylesheet language used to style the web interface.
• JavaScript: Programming language used for client-side scripting and enhancing the interactive aspects of the web interface.

Installation

1. Clone the repository:

   git clone https://github.com/your-username/smart-door-opener.git

2. Set up the hardware:

   • Connect the ESP32 microcontroller to your computer.
   • Attach the distance sensor to the ESP32 as per the hardware schematic provided in the repository.

3. Upload Firmware:

   • Use the Arduino IDE or PlatformIO to upload the firmware to the ESP32. Ensure you have the necessary libraries and drivers installed.

4. Install Backend Dependencies:

   • Navigate to the backend directory of the project and run:

   npm install

5. Start the Backend Server:

   • Run the backend server using:

   npm start

6. Set up the Web Interface:

   • Navigate to the web directory and open index.html in a web browser, or use a local server to serve the HTML files.

7. Configure Environment Variables:

   • Ensure that any necessary environment variables are set up according to the .env file in the backend directory.

8. Access the Application:

   • Open the web interface in your browser. The application should connect to the ESP32 and allow you to control the door remotely.

Future Enhancements

• Implement user authentication for secure access control.
• Integrate additional sensors for enhanced security features.
• Add voice control capabilities through integration with voice assistants.
• Enhance the web interface with more advanced controls and monitoring options.
