This project implements a face recognition-based door access control system using Python, OpenCV, Telegram Bot, and Arduino.

The system captures video frames from a camera, performs face detection using OpenCV's Haar Cascade Classifier, and sends the detected face image to a Telegram bot. The Telegram bot then prompts the user for access approval, and based on the response, it sends a command to an Arduino to either open or keep the door closed.

• Python 3.x
• OpenCV
• telepot (Telegram Bot API wrapper)
• pyserial (Python Serial Library)
• Arduino with appropriate firmware
• Telegram Bot (Bot Token and Chat ID required)

1. Install the required Python packages:

   pip install opencv-python telepot pyserial python-dotenv
   

2. Connect the Arduino to the system and update the serial port in the Python script.

3. Create a .env file in the project root with the following content:

   BOT_TOKEN=your_telegram_bot_token CHAT_ID=your_chat_id

4. Run the Python script: python face_recognition.py

face_recognition.py: Main Python script for face detection and interaction with Telegram Bot and Arduino. haarcascade_frontalface_default.xml: Haar Cascade Classifier for face detection. face_detected.jpg: Image file saved when a face is detected.

Run the Python script. The camera captures frames and detects faces. Detected faces are sent to a Telegram bot. The Telegram bot prompts for access approval. Based on the response, the Arduino is commanded to open or close the door.
