Environmental sensor node provides integrated solution for indoor air quality monitoring

The Sensirion SEN55 sensor module performs accurate measurement of various parameters that affect air quality, including VOCs, NOx, and particulate matter, as well as relative humidity and temperature.


The SEK-SEN5x kit provides a convenient format for evaluating the operation of the SEN5x air quality sensor module. It performs relative humidity and temperature measurements, and tracks volatile organic compounds, nitrogen oxides, and concentrations of particulate matter. The sensor module is equipped with on-board algorithms for converting raw gas measurements to air-quality index outputs, and for accelerating and compensating humidity and temperature readings.

The kit includes:

  • SEN55 gas sensor
  • Adapter cable
  • Jumper wire set

Users of the kit also require an SEK-SensorBridge board.
