Particulate Matter Sensor SPS30
For HVAC and Air Quality Applications
With this new particulate matter sensor, Sensirion expands its range of environmental sensing solutions and opens up a new dimension in indoor and outdoor air quality applications.
The SPS30 particulate matter (PM) sensor represents a new technological breakthrough in optical PM sensors. Its measurement principle is based on laser scattering and makes use of Sensirion's innovative contamination-resistance technology. This technology, together with high-quality and long-lasting components, enables accurate measurements from the device's first operation and throughout its lifetime of more than eight years.
PM2.5 and PM10 refer to particulate matter with particle diameter up to 2.5 microns and 10 microns, respectively, and are among the most dangerous air pollutants. Due to their small size, PM2.5 particles can travel deep into the human lung and cause a variety of health issues; for instance, by triggering asthma attacks or contributing to cardiovascular disease. The SPS30 will enable the implementation of innovative air quality monitoring devices that prevent air pollution damage.

Particulate Matter Sensing for Air Quality Measurements
Author: Dr. Livio Lattanzio, Product Manager Particulate Matter Sensors
Particulate Matter, abbreviated as ‘PM’, is a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. PM includes particles with different characteristics – i.e. shape, optical properties, size and composition ¬– but it is most commonly divided into sub-categories based on the particle size information. Different PM categories are usually reported under the ...
