SDS011 detection principle using a laser, can be obtained in the air suspended particulate matter concentration of 0.3 to 10
microns , stable and reliable data ; built-in fan , digital output , high integration
Feature:l data accuracy : laser detection , stability , consistency, good ;l Quick response : data update frequency of 1Hz;l easy integration : serial output ( or IO port output can be customized ) , comes with fan ;l High resolution : Minimum resolution particle diameter of 0.3 microns ;l standard certification : products have passed CE / FCC / RoHS certification.Scope PM2.5 detector, purifier.working principle Laser scattering theory:
When laser irradiation through the particle detection position will produce a weak scattering of light in a specific direction of the light scattering wave and particle diameter about , you can get different grain through the
waveform classification statistics and conversion formula different size number concentration of particle diameter in real time ,in accordance with the calibration methods with the official unit of uniform concentration .
