With the GLYN VOCSens shield:
measure VOCs, relative humidity and temperature based on Arduino


Environmental conditions have a considerable impact on our well-being, comfort and productivity.
SENSIRION sensor solutions provide detailed and reliable data about the most important

environmental indicators:

  • Relative humidity
  • Temperature
  • Volatile organic compounds (VOCs)
  • CO2 particulate matter (PM2.5/10)

Environmental sensing opens up a host of new possibilities for the development of intelligent devices. Our well-being, comfort and overall energy efficiency can be significantly improved in many applications as a result.

The VOCSens shield from GLYN provides a universal hardware evaluation platform. You can also test VOC sensor SGP30 as well as humidity and temperature sensor SHT31 from SENSIRION based on Arduino UNO.

VOC sensor SGP30 is the world’s first long-term stable sensor for measuring volatile organic compounds.


SENSIRIONs MOXSens® technology enhances the unrivalled durability of the SGP30 against siloxane contamination to ensure outstanding stability and precision in the long term. The SGP relies on several metal oxide sensor elements (pixels) on a chip to deliver detailed air quality signals. A combination of long-term stability and multi-pixel technology makes the SGP the perfect choice for monitoring indoor air quality for mobile applications as well as "Smart Home” and device applications.

The SHT31 humidity sensor is calibrated, linearised and temperature-compensated in the factory.


SENSIRION is a market leader in the development and production of digital relative humidity sensors. 15 years ago, SENSIRION revolutionised the industry with the world’s first digital humidity sensor and then redefined the industry standard with the SHT3x series. The best products on the market, unparalleled know-how and outstanding application SUPPORT make Sensirion the go-to expert for humidity measurement.

VOCSens can be connected to many common MCU evaluation kits with minimal hardware expense.
