- Make sure this fits by entering your model number.
- The SDS011 using principle of scattering,can get the particle concentration between 0.3 to 10um in the air with digital output and built-in fan is stable and reliable.
- Accurate and Reliable: detection, stable, good consistency;Quick response: response time is less than 10 seconds when the scene changes.
- Easy integration: UART output (or IO output can be customized), fan built-in;High resolution: resolution of 0.3ug/m3.
- Scope of application:PM2.5 Detector;Purifier;Air Exchangers;Filtering system.
- Working principle:Using scattering principle:Light scattering can be induced when particles go through the detecting area;The scattered light is transformed into electrical signals and these signals will be amplified and processed
