The SPS30 particle sensor (PM) is a technological breakthrough in optical PM sensors. Its measurement principle is based on laser scattering and utilizes Sensirion's innovative contamination resistance technology. This technology, combined with high-quality and durable components, enables precise measurements from the very first use and throughout its lifespan of over ten years. Furthermore, Sensirion's advanced algorithms provide superior accuracy for various PM types and a higher resolution particle size binning, opening up new possibilities for detecting different types of ambient dust and other particles. With dimensions of just 41 x 41 x 12 mm, it is also the perfect solution for applications where size matters, such as wall-mounted or compact air quality devices.
