Air Quality Detection Sensor

The SDS011 using the principle of laser scattering can get the particle concentration between 0.3 to 10um in the air. It gives direct digital output via serial protocol at 9600bps and also over 2 PWM channels. It with digital output and the built-in fan is stable and reliable.

Nova Fitness SDS011 is a professional laser dust sensor. Fan mounted on sensor automatically sucks air. Sensor uses laser light scattering principle to measure value of dust particles suspended in the air. Sensor provides high precision and reliable readings of PM2.5 and PM10 values.

Any change in environment can be observed almost instantaneously – short respond time below 10 seconds. Sensor in standard mode reports reading with 1 second interval.

  1. PM2.5 Detector
  2. Purifier
  3. Air Exchangers
  4. Filtering system


They are two ways to communicate with SDS011 sensor:

    • digital out (UART)
    • PWM signal (one for PM2.5 and one for PM10)
