Wemos D1 Mini and Nova Fitness SDS011 Laser Dust Sensor - FengtianGu/Sonoff-Tasmota GitHub Wiki
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.

In the Configuration -> Configure Module page, select the following:
- Module Type : 18 Generic
- TX (GPIO01) Serial Out : 101 SDS0X1 Tx
- RX (GPIO03) Serial In : 70 SDS0X1 Rx
Readings are performed every teleperiod seconds (Tasmota Default is 300 seconds = 5 min).
After reboot of the device the displays the SDS011 measurements.
