The Nova SDS011 sensor lets you detect airborne particulate matter with your Metriful MS430 sensor board.

It uses laser scattering assisted by a miniature fan to detect particles with diameters between 0.3 and 10 micrometers.

Our product documentation on GitHub explains how to connect up the SDS011, the MS430 board, and your host system. Connection is easy using three jumper wires - no soldering needed.

A 5 V supply is required - this is present on Raspberry Pi and Arduino when USB powered.

The sensor provides two data outputs (for 0.3 - 2.5 and 0.3 - 10 micrometer particles), one of which can be connected to the MS430 sensor board at any time.


  • Approximate size: 72 x 70 x 23 mm
  • Quiet fan for airflow (fan noise is ~20 dBA at 1 m)
  • Requires a 5 V supply (usually present on USB-powered host systems, including Raspberry Pi and Arduino)
  • Two data outputs - choose one to connect to the Metriful MS430 board


Connecting jumper wires are sold separately.


USB converter

The sensor also comes with a serial to USB converter, for direct connection to your computer (not using your Metriful MS430 board). The manufacturer provides basic graph software for this purpose (not recommended) which can be downloaded at your own risk from their website at
