Datasheet SPS30 Particulate Matter Sensor for Air Quality Monitoring and Control Unique long-term stability Advanced particle size binning Superior accuracy in mass-concentration sensing Small, ultra-slim package Fully calibrated digital output Product Summary The SPS30 Particulate Matter (PM) sensor is a technological breakthrough in optical PM sensors. Its measurement principle is based on laser scattering and makes use of Sensirions innovative contamination- resistance technology. This technology, together with high-quality and long-lasting components, enables accurate measurements from its first operation and throughout its lifetime of more than eight years. In addition, Sensirions advanced algorithms provide superior accuracy for different PM types and higher-resolution particle size binning, opening up new possibilities for the detection of different sorts of environmental dust and other 3 particles. With dimensions of only 41 x 41 x 12 mm , it is also the perfect solution for applications where size is of paramount importance, such as wall-mounted or compact air quality devices.

PM2.5 accuracy is verified for every sensor after calibration using a defined potassium chloride particle distribution. Ask Sensirion for further details on accuracy characterization procedures. 2 PMx defines particles with a size smaller than x micrometers (e.g., PM2.5 = particles smaller than 2.5 m). 3 Validated with accelerated aging tests. Ask Sensirion for further details on accelerated aging validation procedures. Lifetime might vary depending on different operating conditions. www.sensirion.com Preliminary Version 0.9 D1 November 2018 2/20
