Dust Sensor PM Sensor SDS011 High Precision Laser PM2.5 Air Quality Detection Sensor Module Super Dust Sensors Digital Output Applied To Air Quality PM2.5 Monitoring Air Filtering Air Quality Station

Description

Overview: - SDS011 using laser detection principle, can be 0.3 to 10 microns in the air suspended particulate concentration, data is stable and reliable; built-in fan, digital output, high integration Working principle: - The use of laser scattering principle: When the laser beam through the detection of particulate matter will produce weak light scattering, in a particular direction of the light scattering waveform and the particle diameter, through the different particle size of the waveform statistics and conversion formula can be different particles Diameter real-time particle number concentration, according to the calibration method with the official unit of uniform mass concentration.
