Build Your Own Heat Index Monitor with Arduino Uno & DHT22 Sensor

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

The heat index—often called the "feels-like" temperature—combines air temperature and relative humidity to estimate how hot the human body perceives the weather. This kit lets young makers build a desktop weather station that reads live data from a DHT22 sensor and calculates the heat index in real time, displaying it clearly on an LCD screen. No prior coding experience is required; the guided build turns complex environmental sensing into a fun, hands-on learning activity.

What You'll Build

A compact, battery-powered device that instantly shows temperature, humidity, and the computed heat index. You can move it from room to room, place it near a window, or take it outside (in dry weather) to observe how the heat index changes with the environment. The bright 16x2 LCD makes readings easy to see, and the whole setup fits on a breadboard—perfect for school exhibitions or home weather monitoring.

What You'll Learn

• Wiring a DHT22 digital temperature-humidity sensor to Arduino Uno
• Displaying live sensor readings using an I2C LCD with a backpack module
• Programming derived calculations—the heat index formula—from raw sensor data
• The real-world relationship between temperature, humidity, and human comfort

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for students in ATL Tinkering Labs exploring weather monitoring projects, CBSE Class 9–12 learners needing a hands-on physics or computer science demonstration, and first-year B.Tech ECE/EEE students getting started with sensor interfacing. Also a perfect parent-child weekend STEM activity that introduces real-world data analysis.

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.
