Low Power Particle Sensor PM2105L

Low Power Particle Sensor PM2105LPM2105L

PM2105L is a laser particle sensor module for indoor use based on laser scattering technology. This sensor can measure particle concentration size between 0.3μm~10μm exactly and output particle mass concentration PM1.0, PM2.5, PM10 in μg/m³ directly via mathematical algorithm and scientific calibration.
