SDS011 - Laser PM2.5 Air Quality Sen Sensor Digital Output In-built Fan UART

The SDS011 using principle of laser 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. 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. The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter.
