Smart Home Automation Project using Arduino Uno | DHT11, Ultrasonic, LDR & Servo Motor

Welcome to my project presentation!
This video demonstrates my Smart Home Automation System built using Arduino Uno, DHT11 sensor, Ultrasonic sensor, LDR sensor, Servo motor, LEDs, and a 16x2 LCD display.

🔧 Project Overview

The goal of this project is to automate basic home functions such as:

Turning ON the fan automatically when the temperature rises above 30°C

Switching ON the light when it's dark and motion is detected

Simulating door movement using a servo motor

Displaying real-time readings on the LCD screen

💻 Key Components

Arduino Uno

DHT11 Temperature & Humidity Sensor

Ultrasonic Distance Sensor

LDR (Light Dependent Resistor)

Servo Motor

2 LEDs (Fan and Light indicators)

16x2 LCD Display

⚙️ Software Used

Arduino IDE for coding

PICSimLab for simulation and testing

🧠 How It Works

Temperature & Humidity Control:
The DHT11 sensor detects temperature. If it goes above 30°C, the fan turns ON automatically.

Light Automation:
The LDR detects low light, and if someone is detected nearby, the light turns ON.

Door Simulation:
The servo motor mimics a door opening and closing when motion is detected.

Display:
All readings are shown on the LCD, including temperature, humidity, distance, and light level.

🌐 Future Improvements

Cloud data logging using ThingSpeak

IoT mobile app control

Integration with voice assistants like Alexa or Google Assistant

Addition of gas or fire sensors for safety

🎓 Project Purpose

This project was created as part of my internship program to demonstrate practical knowledge of IoT, embedded systems, and home automation concepts.

🏁 Conclusion

This project shows how sensors and automation can make our homes smart, efficient, and energy-saving.
