HVAC Performance Monitor Kit – 3-Gauge Dashboard with Arduino Uno & DHT22

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 your Arduino Uno into a professional‑looking indoor climate dashboard. This kit equips you to build a compact monitor that reads temperature, humidity, barometric pressure, and ambient light, then presents them as three analog‑style gauges on a vivid 1.8‑inch TFT screen — a practical tool for understanding how HVAC systems keep spaces comfortable.

What You'll Build

You'll wire the DHT22, BMP280, and BH1750 sensors to the Arduino, upload the provided code, and instantly see live readings on the TFT display. The dashboard layout arranges three gauges cleanly — temperature/humidity combined, pressure, and light — so you can assess environmental conditions at a glance. The battery snap makes it portable for testing different rooms, while the breadboard lets you experiment further.

What You'll Learn

• Interface digital temperature/humidity, barometric pressure, and light sensors
• Program Arduino to read sensor data and render smooth gauge animations
• Design a clean dashboard layout using TFT graphics libraries
• Calibrate sensor readings and interpret real‑world HVAC metrics

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for students in CBSE Class 8‑12 exploring electronics, ATL Tinkering Labs, and young hobbyists aged 10‑15 who want a hands‑on introduction to sensor integration. It also serves as a solid starter project for B.Tech ECE/EEE first‑year students. If you've ever been curious how thermostats and building management systems read indoor conditions, this kit builds that foundation.

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.
