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.

Important Product Note: With the first time purchase of the GrowFlux CO2 Microclimate Sensor, you must additionally purchase the GFX-AP Connection Access Point to securely connect to the cloud.

Maximum Quantity of Access Points to Sensors 1-60. 


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.
