Smart Fan Auto Speed Kit with Arduino Uno
Smart Fan Auto Speed Kit with Arduino Uno – Build Your Own Temperature-Controlled Smart Fan
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a fan that automatically speeds up as your room gets warmer and slows down when it’s cool — all without you touching a switch. With the Smart Fan Auto Speed Kit, you’ll build exactly that using an Arduino Uno, a DHT11 sensor, and an LCD display. This beginner-friendly project introduces the fundamentals of smart home automation and real-time environmental monitoring.
What You'll Build
You’ll assemble a working smart fan system that reads room temperature using a DHT11 sensor, and proportionally adjusts a 5V DC fan’s speed through an L298N motor driver. The current temperature and fan speed percentage are displayed live on a 16x2 LCD screen, giving you a complete, interactive smart home gadget.
What You'll Learn
- How to interface a DHT11 temperature and humidity sensor with Arduino
- PWM-based motor speed control using an L298N driver
- Displaying real-time sensor data on an I2C 16x2 LCD
- Reading analog signals and mapping them to output values for proportional control

Who This Kit Is For
This kit is ideal for school students from CBSE Class 11-12 exploring physics and electronics projects, and for beginners aged 5-15 who are curious about smart home automation. It’s also a great fit for ATL Tinkering Labs, robotics clubs, and introductory Arduino workshops in Indian schools and colleges.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code in the box to access the AI companion that walks you through every step, or message us on WhatsApp for real-time help.
Can I use this kit for a school science exhibition?
Absolutely — it’s been designed with India’s CBSE and ICSE curriculum in mind, making it an excellent science fair project demonstrating temperature sensing and automation.
Do I need soldering or prior electronics knowledge?
No soldering is needed; the kit uses a breadboard and jumper wires. It’s perfect for absolute beginners with clear, step-by-step instructions.
What if the fan speed seems erratic?
The AI companion can help you calibrate the mapping from temperature to PWM duty cycle, and our support team can assist if the sensor or driver seems faulty.
DHT11 controls fan speed proportionally with temperature. LCD shows temp and fan percent.
