Particle Matter PM2.5 Air Monitor Kit with Arduino Uno + Sensor
Build Your Own PM2.5 Air Quality Monitor with Arduino Uno & PMS5003 Sensor Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
When you walk outside in a bustling Indian city, you’re breathing air that may be filled with fine dust, soot, and smoke. With this kit, you’ll build a portable monitor that measures PM1, PM2.5, and PM10 particles in real time, converts the readings into an AQI scale, and displays health risk levels—from ‘Good’ to ‘Hazardous’—on a bright OLED screen. It’s a hands-on way to see the air quality index for your own neighbourhood and make informed decisions.
What You'll Build
You’ll assemble a compact sensor station that draws ambient air through the PMS5003 laser particle counter, processes the data with an Arduino Uno, and shows PM2.5 and AQI values on a 0.96-inch OLED along with a health advisory. The device can run on a 9V battery, so you can take it outdoors or mount it in your room. By the end, you’ll have a reliable air quality monitor that rivals off-the-shelf devices costing several times more.
What You'll Learn
- Interface the PMS5003 particle sensor via UART and parse PM1, PM2.5, and PM10 data streams.
- Convert particle concentrations into AQI (Air Quality Index) and health risk categories using international standards.
- Drive a 0.96-inch OLED display over I2C to show real-time readings and colour‑coded risk levels.
- Use pull‑up resistors and decoupling capacitors to stabilise sensor and display signals on a breadboard.

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students preparing a physics or environmental science investigatory project on air pollution, B.Tech ECE/EEE undergraduates tackling a mini-project on sensor systems, and teams at Smart India Hackathon exploring real-time environmental monitoring. It’s also a great resource for ATL Tinkering Labs and IIT/NIT workshop participants who want to move from concept to a working prototype in a weekend.
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 on the box to chat with our AI build companion, trained specifically on this PM2.5 monitor project. You can also reach us on WhatsApp for real-time help.
Can this kit measure air quality outdoors?
Yes, the PMS5003 sensor draws air through an internal fan and works best in still air. You can power the kit with a 9V battery (not included) to take it outdoors, but protect it from rain and strong wind.
How accurate are the PM2.5 readings compared to commercial monitors?
The PMS5003 laser sensor is widely used in reference-grade DIY monitors and compares well with devices like PurpleAir. It may show slight variations due to humidity, but for educational and indicative monitoring it's highly reliable.
Do I need any prior programming experience?
This kit is intermediate-level. You should be comfortable uploading code to an Arduino Uno, but our AI companion will guide you through the wiring and sample code line by line.
PMS5003 laser particle sensor reads PM1, PM2.5 and PM10. OLED shows AQI and health risk level.
