Build a Real-Time Air Quality Index Dashboard with Arduino Uno & Precision Sensors

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

Turn your Arduino Uno into a standalone air quality monitoring station that calculates the AQI using real PM2.5, CO2, and VOC data. The colour TFT screen instantly shows a traffic light system—green for safe, yellow for moderate, red for unhealthy—along with a plain-language recommendation like ‘Open windows’ or ‘Wear a mask outdoors.’ This dashboard works without any Internet connection, making it ideal for school labs, hackathons, and portable environmental sensing.

What You'll Build

You’ll assemble a fully functional AQI monitor on a breadboard that continuously samples airborne particles and gases. The display updates every few seconds with PM2.5 concentration, CO2 ppm, the estimated AQI number, and the coloured traffic light. The dashboard also logs peak values, so you can track air quality changes over a lab session or a full day—exactly what’s needed for a compelling science exhibit or a data-driven hackathon demo.

What You'll Learn

• Read PM2.5, CO2, and VOC sensors simultaneously with Arduino Uno
• Convert raw sensor readings into a unified Air Quality Index score
• Drive a 1.8‑inch colour TFT display to show live data, traffic light, and text alerts
• Implement conditional logic for health recommendations based on real‑time sensor thresholds

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This AQI Dashboard Kit is designed for CBSE Class 11–12 students building informatics or environmental projects, B.Tech ECE/EEE undergraduates prototyping sensor networks, and teams participating in the Smart India Hackathon or ATL Tinkering Lab innovation challenges. It’s also a strong starting point for anyone preparing an air quality project for a college fest, state-level science exhibition, or an IIT/NIT workshop.

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.
