Fan Temperature Controller Kit – Master PWM and Sensor Integration with Arduino Uno

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 spins faster as your room warms up, without you touching a switch. This kit lets you build exactly that: an Arduino-based temperature controller that reads ambient heat through an LM35 sensor, adjusts the fan’s speed proportionally using PWM, and displays both temperature and fan percentage on a backlit LCD. It’s a perfect introduction to closed-loop control systems that you can see and feel.

What You'll Build

You’ll assemble a compact circuit on a breadboard, connect the components, and load the pre-written logic onto your Arduino Uno. The finished project becomes a self-regulating cooling system: place the LM35 near a heat source, and watch the fan speed ramp up in real time. The 16x2 LCD shows the current temperature in degrees Celsius and the corresponding fan duty cycle, giving you a clear, numeric feedback loop.

What You'll Learn

• Interfacing an analog temperature sensor (LM35) with Arduino’s ADC
• Generating and controlling PWM signals to drive a DC fan via L298N
• Displaying sensor data on a 16x2 LCD using an I2C backpack
• Writing proportional control logic that links temperature change to fan speed

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Crafted for CBSE Class 9–12 students exploring sensor-based projects, hobbyists in ATL Tinkering Labs, and parents introducing electronics to children aged 5–15. It’s equally useful for B.Tech ECE/EEE first-year labs demonstrating PWM and open-loop control. If you’ve ever wanted a hands-on project that moves, reacts, and teaches real embedded systems concepts, this is your starting point.

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.
