Sensirion to present particulate matter sensor at IoTE 2018

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, Sensirion’s algorithms provide enhanced 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 particles. With dimensions of only 41 x 41 x 12 mm, it is suitable for applications where size is of paramount importance, such as wall-mounted or compact air-quality devices.

Traditional optical PM sensors suffer from contamination, the company reports, which causes output degradation. Contamination results from continued dust and particle accumulation on the sensor’s optical components, namely the light source (usually a laser or LED) and the photodetector. Consequently, devices integrating these PM sensors stop working correctly after some time, which results in malfunctions, user complaints, maintenance, service, and/or part replacement. Sensirion’s proprietary contamination-resistance technology and long-lasting components provide the SPS30 with robustness, long-term stability, and high accuracy, together with a lifetime of more than eight years in continuous mode operating 24 hours per day.
