Build a Portable PM2.5 Air Pollution Monitor and AQI Data Logger with Arduino Uno

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

With rapid urbanisation, understanding air pollution is more critical than ever. This kit lets you build a portable monitor that logs PM2.5 levels at any location - near a busy road, inside a classroom, or in a park. By comparing real data against a clean-air baseline, you'll calculate AQI and create compelling graphs for your science project or research paper.

What You'll Build

You'll assemble a battery-powered air quality station that reads PM2.5 concentrations from a PMS5003 laser particle sensor, timestamps every reading with a real-time clock, displays live values on an OLED screen, and saves all data to a microSD card. Back home, you can analyse how pollution levels vary with time and place, producing professional-grade AQI charts that demonstrate a deep understanding of environmental health.

What You'll Learn

• Interface a laser-based particle sensor (PMS5003) with Arduino to measure PM2.5 in ?g/m�.
• Use a DS3231 RTC module to timestamp sensor readings for accurate data logs.
• Calculate the Air Quality Index (AQI) from raw PM2.5 data using standard EPA breakpoints.
• Visualise and interpret air quality trends by plotting time-series graphs of logged data.
