Datasheet SPS30 Particulate Matter Sensor for Air Quality Monitoring and Control Unique long-term stability Advanced particle size binning Superior precision in mass concentration and number 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 precise measurements from its first operation and throughout its lifetime of more than ten years. In addition, Sensirions advanced algorithms provide superior precision 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 particles. 3 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.

Deviation to reference instrument is verified in end-tests for every sensor after calibration. 4 PM4 and PM10 output values are calculated based on distribution profile of all measured particles. 5 Time after starting Measurement-Mode, until a stable measurement is obtained. 6 Lifetime is based on mean-time-to-failure (MTTF) calculation. Lifetime might vary depending on different operating conditions. www.sensirion.com Version 1.0 D1 March 2020 2/26
