The introduction by Sensirion of its new SPS30 particulate matter sensor marks a breakthrough in optical sensor technology, offering more stable performance and a longer operating lifetime thanks to greatly improved resistance to contamination.

The SPS30 uses a laser scattering method for measuring the concentration of particulates in the atmosphere. Comprised of high-quality and long-lasting components, the SPS30 provides accurate measurements from its first operation and throughout its lifetime of more than eight years of continuous operation.

In addition, Sensirion’s advanced algorithms provide accurate measurement results for different types of particulates. Higher-resolution particle size binning enables new use cases and device-specific actions based on the detected particle composition of various types of environmental dust and other particles.

The SPS30 also benefits from Sensirion’s proprietary contamination-resistance technology. Traditional optical particulate matter sensors suffer from contamination, which impairs the sensor’s performance. Contamination results from dust and particle accumulation on the sensor’s light source and photodetector. The SPS30’s contamination resistance ensures longterm stability and high accuracy.

The SPS30 measures 41mm x 41mm x 12mm, which means that it is suitable for use in wall-mounted or compact air-quality devices.
