Project Description:

The Smart Home Appliance IoT Hub is a centralized system that allows users to monitor, control, and automate multiple smart home appliances (like lights, fans, ACs, TVs, refrigerators, etc.) from a single web-based dashboard or mobile app using IoT technology. The system connects household devices to the internet, making it possible to operate them remotely, schedule actions, and track usage patterns.

This project enhances energy efficiency, home security, and user convenience, creating a truly smart living environment.

Technologies Used:

• Backend: PHP / Java / Node.js

• Frontend: HTML, CSS, Bootstrap, JavaScript

• Database: MySQL / MongoDB / Firebase

• IoT Hardware:

  • Microcontroller: ESP32 / ESP8266 / Arduino

  • Relays / Smart Plugs – to control appliances

  • Sensors: Temperature, humidity, motion, light

  • Wi-Fi Module – for real-time connectivity

  • Voice Integration (Optional): Alexa / Google Assistant

Core Features:

1. Appliance Control:

   • Turn devices ON/OFF from web or mobile interface in real-time.

2. Scheduling & Automation:

   • Set schedules (e.g., turn on AC at 7:00 PM).

   • Automate based on sensor data (e.g., turn off lights when room is empty).

3. Real-Time Monitoring:

   • View the status (on/off), room temperature, device usage time.

4. Usage Analytics:

   • Track daily/monthly power consumption per appliance.

5. Voice Command Integration (Optional):

   • Use smart assistants like Alexa or Google Home for voice-based control.

6. Mobile/Web Notification:

   • Get alerts for unusual activity or device failures.

How It Works:

1. User logs into the web/mobile dashboard.

2. Commands (e.g., "Turn on light") are sent to the backend.

3. Backend communicates with microcontrollers via Wi-Fi.

4. Microcontrollers trigger relays connected to home appliances.

5. Sensor data (e.g., temperature, motion) is collected and displayed.

6. Usage statistics are stored and visualized on the dashboard.
