The PPD42 sensor is a cost-effective way to detect airborne particulate matter together with your Metriful MS430 sensor board.

Our product documentation on GitHub explains how to connect up the PPD42, 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.


  • Approximate size: 59 x 45 x 19 mm
  • Detects particles larger than 1 micrometer
  • Uses a silent convection method for airflow
  • Requires a 5 V supply (usually present on USB-powered host systems, including Raspberry Pi and Arduino)


Connecting jumper wires are sold separately.
