Below is a screenshot of the fan control web interface:

Web-Based Fan Controller using Raspberry Pi

This IoT project allows users to control a fan remotely using a web interface built with Flask, Python, and Raspberry Pi GPIO PWM signals.

Features

• Wi-Fi based fan ON/OFF control
• Real-time PWM speed adjustment (0%–100%)
• Lightweight Flask server with AJAX functionality
• GPIO pin management and PWM signal generation
• (Optional) TMP36 sensor integration

Technologies Used

• Python 3
• Flask
• RPi.GPIO library
• HTML5, CSS3, JavaScript (AJAX)

Setup Instructions

1. Install the required Python packages:

   pip install -r requirements.txt

2. Run the application:

   python app.py

3. Access the fan controller UI by visiting:

   http://<your-raspberrypi-ip>:5000/fanControl
   

Notes

• Ensure you have the necessary GPIO permissions (sudo if needed).
• Tested on Raspberry Pi 4 with Raspberry Pi OS Lite (64-bit).
