What is IoT-Based Home Automation?
IoT home automation allows users to remotely control household appliances using the internet. Here’s how it works:
Sensors & Controllers – Devices like temperature sensors, motion detectors, and light sensors collect data.
Microcontroller (Arduino/Raspberry Pi) – The brain of the system processes the data.
Communication Network (Wi-Fi/Bluetooth) – Connects the system to your smartphone.
Mobile App or Web Interface – The user can send commands remotely.

Materials Required
Component | Description |
Arduino/Raspberry Pi | Controls and processes automation commands |
Relay Module | Switches appliances ON/OFF |
Temperature Sensor | Measures room temperature |
Motion Sensor | Detects movement |
Smartphone App | Used for remote control |
Step-by-Step Guide to Building the System
Step 1: Setting Up Arduino/Raspberry Pi
Install Arduino IDE or Raspberry Pi OS.
Update the system using:
sudo apt update && sudo apt upgrade
Step 2: Install Required Libraries
Run the following command to install necessary Python libraries:
pip install requests flask gpiozero
Step 3: Connect the Sensors and Relay Module
Use the circuit diagram to connect sensors to Arduino or Raspberry Pi.
The relay module is used to switch home appliances ON/OFF.
Step 4: Write the Code for Automation
Use this Python code to control appliances via Wi-Fi:
from gpiozero import LED
from flask import Flask
app = Flask(__name__)
relay = LED(17)
@app.route("/on")
def turn_on():
relay.on()
return "Appliance Turned ON"
@app.route("/off")
def turn_off():
relay.off()
return "Appliance Turned OFF"
if __name__ == "__main__":
app.run(host="0.0.0.0", port=5000)
Step 5: Control Home Appliances via Smartphone
Open a browser and enter http://your-device-ip:5000/on to switch ON the device.
Enter http://your-device-ip:5000/off to switch it OFF.

Troubleshooting Common Issues
1. Devices Not Responding
Causes: Weak Wi-Fi, incorrect wiring, power issues.
Solution: Check Wi-Fi, verify wiring, and ensure proper power supply.
2. App Not Connecting
Causes: Wrong IP address, firewall restrictions, misconfiguration.
Solution: Update IP, disable firewall blocks, restart the app.
3. Relays Not Switching
Causes: Faulty relay, incorrect GPIO pin setup, low power.
Solution: Test relay separately, check GPIO settings, ensure sufficient voltage.
4. Sensors Giving Wrong Readings
Causes: Environmental interference, loose connections, faulty sensor. Solution: Reposition sensors, secure wiring, replace if needed.
Real-World Applications of IoT in Home Automation
