Breakthrough in environmental sensing technology: Sensirion presents long-term stable particulate matter sensor

This summer, Sensirion, Swiss expert in environmental sensing, announced the SPS30, a long-term stable, high-accuracy particulate matter sensor at this year’s IoTE 2018 in Shenzhen, China. 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 accurate measurements from its first operation and throughout its lifetime of more than eight years. In addition, Sensirions advanced algorithms provide superior 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 mm³, it is the perfect solution for applications where size is of paramount importance, such as wall-mounted or compact air quality devices.

Traditional optical PM sensors suffer from contamination, 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. Sensirions proprie-tary contamination-resistance technology and long-lasting components provide the SPS30 with unmatched robustness, unique long-term stability and high accuracy, together with a lifetime of more than eight years in continuous mode operating 24 hours/day.
