Cyclist Air Quality Tracker Kit with Arduino Uno — Your Portable PM2.5, CO2 & AQI Dashboard

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

Cyclists in Indian cities inhale more than just fresh air — they breathe PM2.5, vehicle exhaust, and rising CO₂. This kit puts an environmental lab in your hands, letting you build a handlebar-ready device that reads particulate matter, toxic gases, and carbon dioxide, then converts them into a single AQI score and a traffic-light recommendation on a colour TFT screen.

What You'll Build

You'll assemble a compact monitoring station around the Arduino Uno that continuously samples air via the PMS5003 laser particle counter, MQ-135 gas sensor, and MH-Z19B CO₂ sensor. The on-board logic fuses the three readings into a calibrated AQI number and displays a green, amber, or red indicator along with a simple text recommendation — “Good to ride”, “Wear a mask”, or “Avoid cycling”. The circuit fits neatly on a breadboard and can be powered by a 9V battery, so you can take it on real rides.

What You'll Learn

• Interfacing digital laser particle sensors over UART and parsing real-time PM2.5/PM10 data
• Reading analogue gas sensor outputs and calibrating against known AQI breakpoints
• Communicating with an NDIR CO₂ sensor via serial protocol
• Programming a colour TFT display to show live AQI, traffic lights, and ride advice

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11–12 students exploring environmental sensing, B.Tech ECE/EEE undergraduates tackling IoT mini-projects, and Smart India Hackathon participants needing a functional AQI prototype. It also fits perfectly into ATL Tinkering Labs where students want to build a real-world gadget that addresses urban air pollution — a challenge every Indian city faces.

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.
