Feature

●Scope of application:PM2.5 Detector;Purifier;Air Exchangers;Filtering system
●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
●The SDS011 using principle of scattering,can get the particle concentration between 0.3 to 10um in the air.It with digital output and built-in fan is stable and reliable.
●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 PM sensor SDS011 High precision laser pm2.5 air quality detection sensor module Super dust dust sensors, digital output Note : It supports 5V power supply voltage, output signal TTL Is 5V, higher than this voltage, the product will burn out
