Particulate Matter Sensor SPS30

For HVAC and Air Quality Applications

Sensirion expands its range of environmental sensing solutions with this new particulate matter sensor, and opens up a new dimension in outdoor and indoor air quality applications.

The SPS30 particulate matter (PM) sensor signifies a new technological breakthrough in optical PM sensors. Its measurement principle is based on laser scattering and utilizes Sensirion’s innovative contamination-resistance technology. This technology, along with superior-quality and long-lasting components, enables correct measurements from the device’s first operation and during the course of its lifetime of over eight years.

PM2.5 and PM10 denote particulate matter with particle diameter up to 2.5 µm and 10 µm, respectively, and are among the most hazardous air pollutants. Owing to their small size, PM2.5 particles can enter deep into the human lung and cause several health issues; for example, by causing asthma attacks or contributing to cardiovascular disease. The SPS30 will enable the implementation of groundbreaking air quality monitoring devices that stop air pollution damage.
