▪ Environmental monitoring Description
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. Features ▪ The smallest size of available measurement: 0.3μm
▪ Real-time output PM1.0, PM2.5, PM10 in μg/m3 available
▪ High accuracy, high sensitive and quick response (≤8s)
▪ Signal output optional: UART, I²C, PWM
▪ RoHS and Reach compliant
▪ Air inlet and outlet on different side …
