Description

Track in real-time PM2.5 dust concentrations. It’s super easy to set up and start using right out of the box with our example Arduino code, along with pre-soldered headers and pre-connected wires.

This high precision dust sensor can also be used to measure PM10 in addition to PM1.0. PM1.0 isn’t the concentration standard commonly used by governments or agencies, but it’s just as, if not more important than PM2.5+. 

Get a reliable reading of dust concentrations between 0.3 to 10um using a light scattering analysis method. This method determines particle motion and density by measuring fluctuations in the intensity of scattered light. The microprocessor then calculates equivalent particle diameter and the number of particles with different diameter per unit volume. This technique enables users to measure very small particles, particles that fall below even 1.0um in size.

We’ve written an example Arduino code for you, which you can find in the tutorial. With this code, you can measure: PM1.0, PM2.5, and PM10.0 concentrations in both standard & environmental units (# ug/m3)

You can use any Arduino or Arduino-compatible microcontroller to read the digital sensor data. It’s a nifty little module that will help you create an accurate air quality or weather-related project.
