Air Pollution Dispersion Modeller
Model Air Pollution Dispersion at Multiple Heights with an Advanced Arduino Mega Logger
Every part needed, pre‑tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3‑5 days.
You’ll construct a vertical sensor array that captures real‑time air quality at three different heights, logging CO, ammonia, and smoke concentrations to an SD card with precise timestamps. Whether it’s a final‑year engineering project, a Smart India Hackathon prototype, or a citizen‑science initiative, this kit delivers high‑resolution pollution gradient datasets ready for analysis.
What You'll Build
Assemble a robust data logger using an Arduino Mega, three MQ‑135 sensors, and one MQ‑7 sensor mounted on M3 standoffs at different heights. An OLED display shows live readings while the DS3231 real‑time clock timestamps every measurement saved to the microSD. The result is a portable environmental station that reveals how pollution disperses vertically — invaluable for urban planning, agriculture, and public health studies.
What You'll Learn
- Interfacing multiple analog gas sensors with Arduino Mega and managing power distribution across a multi‑node array.
- Timestamping sensor data using a DS3231 RTC and writing structured CSV logs to an SD card module.
- Calibrating MQ‑series sensors for relative measurements and understanding cross‑sensitivity in a vertical profile.
- Designing a physical sensor mast with soldered headers on prototype PCBs, minimising signal interference between channels.

Who This Kit Is For
This kit is built for engineering students (B.Tech ECE, EEE, Environmental) tackling Smart India Hackathon challenges on air quality, for final‑year IoT project groups at NITs, VIT, or BITS Pilani, and for researchers prototyping low‑cost vertical pollution monitoring networks. If you’ve tinkered with Arduino basics and want a real‑world, data‑intensive build, this is your project.
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.
What if I get stuck during the build?
Scan the QR code to launch the AI companion, which offers step‑by‑step debugging and circuit checks. If you need human help, WhatsApp us — we’ll respond within hours.
Can I add more sensors or extend the height?
Yes, the Arduino Mega has spare analog and I2C pins. You can add extra MQ sensors or a BME280, and the M3 standoffs let you extend the mast easily.
How do I calibrate the MQ sensors?
The AI companion guides you through setting a clean‑air baseline and adjusting code constants. For absolute ppm values you’d need reference gases, but the relative gradients are fully valid for dispersion studies.
Is soldering required?
Yes — the kit includes an iron and solder, and you’ll solder resistors, capacitors, and sensor headers onto the prototype PCBs. The AI companion walks you through each joint, no prior experience needed.
Multiple MQ sensors at different heights model vertical pollution gradient. Logs to SD with timestamps.
