Particulate matter sensors

Sensirion’s particulate matter (PM) sensors are designed for a wide range of applications and provide real-time data on mass concentration and particle number across various particle sizes, including PM1.0, PM2.5, PM4, and PM10. Our PM sensors are based on an optical measurement principle using laser light scattering. Onboard algorithms analyze the scattered light to accurately determine particle size distribution and mass concentration. With an integrated ASIC, all signal processing is handled internally, eliminating the need for external processing. With proven long-term durability and compact design, our PM sensors deliver reliable air-quality measurements across diverse environments.
