Product Overview
SDS011 uses the laser detection principle to obtain the concentration of suspended particles in the air from 0.3 to 10 microns. The data is stable and reliable. It has a built-in fan, digital output, and high integration.
Product Features
Accurate data: laser detection, stable and consistent;
Fast response: scene change response time is less than 10 seconds;
Easy to integrate: serial port output (or IO port output can be customized), built-in fan;
High resolution: the minimum diameter of the resolved particles is 0.3 microns;
Scope of application
PM2.5 detector, purifier.
Working principle
It works on the principle of laser detection: a dedicated laser module generates a specific laser beam. When particles pass through, their signals will be detected by the ultra-sensitive digital circuit module. The particle count and particle size are obtained through intelligent identification and analysis of the signal data. The particle size distribution and mass concentration conversion formula are obtained based on professional calibration technology, and finally the mass concentration consistent with the official unit is obtained.
