Sensirion SPS30

€ 39,00

Sensirion SPS30 Particulate Matter (PM) Sensor features a measurement principle based on laser scattering and uses Sensirion's innovative contamination-resistance technology. This technology, together with high-quality and long-lasting components, enables accurate measurements from the device's first operation throughout its lifetime of more than eight years. Advanced algorithms provide superior precision for different PM types and higher-resolution particle size binning. This allows the detection of different sorts of environmental dust and other particles. With dimensions of only 41mm x 41mm x 12mm, the SPS30  is ideal for applications where the size is of paramount importance, such as wall-mounted or compact air-quality devices.
