Smart Automatic Window System with Environmental Sensing – Advanced Home Automation Project Kit

Description

🌤️ Project Overview

The Design and Development of Smart Window System is a modern automation project aimed at enhancing energy efficiency, safety, and comfort in buildings.
This system senses environmental parameters such as temperature, light intensity, and rain, and automatically controls the window glass movement and fan ventilation using actuators and sensors interfaced with an Arduino controller.

By integrating linear actuators, DC fans, and sensors, the window system automatically opens to allow airflow when conditions are favorable and closes during rain or excessive heat — ensuring an intelligent, hands-free operation.

This project merges embedded systems, mechanical automation, and environmental monitoring, making it a perfect smart home and sustainable technology prototype.

⚙️ Working Principle

1. Sensing Environment:

   • The system continuously measures temperature, light intensity, and humidity/rain detection through corresponding sensors.

   • Example: DHT11 (temperature/humidity), LDR (light), and rain sensor module.

2. Microcontroller Processing:

   • The Arduino Uno acts as the central processing unit.

   • It interprets sensor data and decides whether to open or close the window.

3. Automated Actuation:

   • The linear actuator operates the sliding window based on the control signal.

   • A DC fan provides ventilation when internal air circulation is required.

   • Relay drivers control both actuator and fan operations safely.

4. System Behavior Example:

   • If temperature rises → window opens & fan starts.

   • If rain is detected or light intensity drops → window closes automatically.

   • LCD display shows real-time system parameters.

This makes the system energy-efficient, weather adaptive, and user-independent.

🔩 Key Features

• Fully automatic operation – reacts to environmental changes.

• Sensors for weather detection – monitors temperature, light, and rain.

• Arduino-controlled system – precise and reliable automation.

• Linear actuator – ensures smooth and quiet window motion.

• Ventilation fan integration – enhances airflow when window opens.

• LCD display – shows sensor readings and system status.

• Compact prototype – ideal for labs, projects, or small home models.
