Product information "Gravity: PM2.5 Air Quality Sensor"

As the most basic part of life, air is attracting more and more attention, for example, the most common PM2.5, PM1.0, PM10, etc. Keeping an eye on the quality of the air we breath is becoming quite important.

DFRobot brings you this Air Quality Sensor that can measure particulate matter like PM2.5, PM1.0, PM10.

With easy-to-use Gravity interface, the air quality sensor works well with most main-controllers. And we provide you with relevant sample codes to help you quickly build up air quality monitoring projects.

Based on the principle of laser scattering, the PM2.5 air quality sensor employs a digital universal particle sensor that can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume, which is particle concentration distribution, and then convert to concentration and output via I2C interface.

The sensor can be embedded in various instruments and meters or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.

It is typically suitable for smoking rooms, kitchens, hot springs, bathrooms and other environments.

Gravity: PM2.5 Air Quality Sensor

How does the sensor work?

This sensor adopts the principle of laser scattering, that is, to make the laser irradiate the suspended particles in the air to produce scattering, and at the same time collect the scattered light at a certain angle, and obtain the curve of the intensity of the scattered light with time. Furthermore, the microprocessor, based on the MIE theory algorithm, obtains the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume.
