Particulate Matter Sensor

Product Summary：

    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 Sensirion’s innovative contaminationresistance technology. This technology, together with high-quality and long-lasting components, enables precise measurements from its first operation and throughout its lifetime of more than ten years. In addition, Sensirion’s advanced algorithms provide superior precision 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 also the perfect solution for applications where size is of paramount importance, such as wall-mounted or compact air quality devices.

Technology：

• Proprietary contamination-resistance technology and long-lasting components.

• Laser-based scattering principle and advanced algorithms.

• Accurate high-resolution particle size binning.

• Small, ultra-slim package.

• Fully calibrated digital output for PM number and mass concentration values.

• UART and I2C interfaces.

Benefits：

• Lifetime of more than ten years while operating continuously for 24 hours/day.

• No need for cleaning and/or maintenance, thus avoiding problems related to sensor drift or malfunction.

• Precise measurements for different types of dust and other particles.

• Enables new types of use cases and device-specific actions based on detected particle composition.

• Easy to integrate into devices where size and space are limited.

• Simple interfacing and read-out of multiple outputs.

Sensor Specifications：

¹ Specified for PM2.5 at 25℃ using potassium chloride salt particles and the TSI DustTrak^TM DRX Aerosol Monitor 8533 as a reference.

² PMx defines particles with a size smaller than "x" micrometers (e.g., PM2.5 = particles smaller than 2.5 μm).
