Build a PMV Thermal Comfort Index Monitor with This Arduino Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Transform raw temperature and humidity data into a meaningful comfort indicator. This kit uses a DHT22 sensor, an air speed simulation input, and a vivid TFT screen to compute and display the industry-standard Predicted Mean Vote (PMV) thermal comfort index. Whether you're tuning an air conditioning zone or presenting a smart classroom idea, you'll hold a complete handheld monitor that reads exactly like a professional environmental chamber—but built by you.

What You'll Build

You'll assemble a handheld monitor that reads real-time DHT22 temperature and humidity, lets you dial in air speed through a potentiometer, and computes the PMV index on the Arduino. The 1.8-inch TFT instantly paints a colour band from cool blue to warm red, mapping the seven-point comfort scale. The result is a compact tool that demonstrates how thermal sensation depends on the triple combination of heat, moisture, and airflow—perfect for science fairs, HVAC hobby projects, or indoor climate awareness campaigns.

What You'll Learn

• Wire and read a DHT22 digital temperature and humidity sensor over a single data pin
• Drive an ST7735 TFT display to render dynamic colour gradients and numeric readouts
• Implement the Predicted Mean Vote (PMV) thermal comfort model using standard formulas
• Simulate air speed input through a potentiometer and incorporate it into the PMV equation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11–12 students exploring environmental monitoring and physics projects will find the PMV model directly links theory to a hands‑on device. B.Tech ECE and Mechanical Engineering first‑years can use it to study sensor fusion and indoor climate control. ATL Tinkering Labs and Smart India Hackathon teams working on green building, HVAC, or wellness tech challenges will gain a ready‑made prototyping platform that demonstrates actual thermal comfort standards.

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.
