The GrowFlux Microclimate CO2 Sensor can remotely monitor microclimates and CO2 levels, making critical measurements available from anywhere on your smartphone or PC. With the wireless and battery-powered design, the sensor can be placed anywhere among the crop, allowing growers to pinpoint CO2 enrichment dead zones and stratification.

CO2 supplementation allows growers to boost crop yield by 20-30%; CO2 supplementation paired with lighting control can help growers significantly reduce the lighting energy needed to grow a crop.

The GrowFlux Microclimate CO2 sensor features a splash-resistant housing with a hydrophobic gas sensing membrane and is suitable for use in greenhouses and indoor farms.

Cloud-based data logging in GrowFlux’s platform helps growers collect the right data every time while eliminating the manual labor associated with setting up sensors, downloading data, and analyzing raw data. Certain data logging features require a subscription (See Below). Battery life ranges from 2-12 months, depending on the reporting interval.


  • Smartphone, browser, and software API access
  • Cloud-based data logging (some features require subscription)
  • Precision monitoring of CO2 levels, temperature, humidity, and atmospheric pressure
