🚪 Automatic Door Control System

An IoT-based system that allows for manual and automatic door control to enhance security and track traffic. Developed with Arduino and Raspberry Pi using Flask, MySQL, and web technologies.

🔧 Features

✅ Automatic and Manual Operation Modes

• Auto Mode

  • Opens the door during the day when a person is detected
  • Keeps the door closed and triggers an alarm at night if someone is detected

• Manual Mode

  • Allows store owners to override the system and directly control door and alarm states

---

👁 Sensor Integration

• Ultrasonic Sensor (HC-SR04): Detects proximity and motion (digital input)
• Photoresistor (LDR): Detects ambient light levels to distinguish between day and night (analog input)

---

⚙ Actuator Control

• Servo Motor (SG90): Opens or closes the door based on logic conditions
• LED Alarm Indicator: Lights up during night intrusions (in either manual or automatic mode)

---

🧠 Edge Computing with Raspberry Pi

• Processes sensor data
• Logs data to a MySQL database
• Hosts a Flask web server with real-time dashboard access

---

🌐 Web-Based Dashboard

Built with Flask (Python) + HTML/CSS/JavaScript Features:

• Real-time log display (distance, light level, door state, alarm state, control mode)

• Control toggles for:

  • Manual/Auto mode
  • Door state
  • Alarm state

• Customer traffic counter based on door open events

• Responsive UI for remote monitoring and control

---

💾 Data Logging

• All sensor readings and actuator states are stored in a MySQL database with timestamps
• Supports traffic analysis and performance tracking

🚀 How to Use

1. Upload Arduino Code Open the Arduino IDE and upload the sketch at: /edge_device_controller/edge_device_controller.ino

2. Identify the Arduino Serial Port

   • Plug your Arduino into the Raspberry Pi or computer
   • Use Arduino IDE or run ls /dev/tty* (Linux) to find the connected port (e.g., /dev/ttyUSB0 or /dev/ttyACM0)

3. Edit Serial Port in Python Script In edge_server.py, locate the line:

   ser = serial.Serial('/dev/ttyACM0', 9600, timeout=1)

   Replace '/dev/ttyACM0' with your actual port from Step 2

4. Install Dependencies Run the following command in your terminal:

   pip install -r requirements.txt

5. Run the Edge Server In the project directory, execute:

   python edge_server.py

6. Open the Web Interface

   • Visit the local address shown in your terminal

   • Use the interface to:

     • Monitor sensor readings and actuator states
     • Toggle control modes
     • Open/close the door or toggle the alarm
     • Count traffic within a given time range
