Nova Fitness SDS011 PM2.5 PM10 Laser Dust Sensor (Serial)

The SDS011 using principle of laser scattering,can get the particle concentration between 0.3 to 10µm in the air. It with digital output and built-in fan is stable and reliable.

Accurate and Reliable: laser 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 0.3µg/m3;

Measurementparameters PM2.5, PM10 Range 0.0-999.9µg /m3 Rated voltage 5V Rated current 70mA±10mA

See Nova Fitness SDS011 PM2.5 PM10 Laser Dust Feinstaub Sensor (German) for more information.
