Growlink LINKS ClimaLINK Climate Sensor with CO2 — Temperature, Humidity, Light, VPD & CO2 Monitor

Add Real-Time CO2 Data to Your Canopy Climate Picture

Facilities running active CO2 supplementation need to know their enrichment levels are landing where they're supposed to, and this version of ClimaLINK answers that by adding carbon dioxide tracking to the same temperature, humidity, light, and VPD readings the standard sensor already provides. That gives a facility five parameters from one device instead of running a separate standalone CO2 monitor.

CO2 tends to stratify unevenly in an enclosed room, settling differently near the floor or ceiling depending on airflow, so this sensor keeps the same aspirated design as the standard ClimaLINK to make sure its CO2 reading reflects conditions at the canopy rather than wherever the air happens to be still.

Key Features & Benefits

• Real-Time CO2 Monitoring: Tracks carbon dioxide concentration to keep supplementation within target ranges and avoid over-injection.
• Adds a Fifth Parameter: Combines CO2 with the temperature, humidity, light, and VPD data of the standard ClimaLINK.
• Aspirated Design for CO2 Accuracy: Active airflow prevents stratified CO2 pockets from skewing the reading.
• Automatic VPD Calculation: Still computes VPD in real time alongside the added CO2 data.
• One Sensor Feed, Coordinated Response: Lets CO2 injection, HVAC, and lighting systems work from the same data stream.

Who Should Use This

Cultivators running active CO2 enrichment who want that data alongside temperature, humidity, VPD, and light in a single feed are the direct fit for this sensor, especially operations using Growlink automation to control CO2 injection equipment.

About Growlink

Growlink, founded in 2015, builds tank and nutrient monitoring hardware as part of its broader LINKS ecosystem, feeding sensor data into the Growlink OS platform for automated response.

Frequently Asked Questions

What is the difference between this sensor and the standard ClimaLINK?

The standard ClimaLINK monitors temperature, humidity, light, and VPD. This version adds a fifth parameter, real-time CO2 concentration, making it the better choice for operations running CO2 supplementation.

Why does CO2 monitoring matter for indoor growing?

CO2 is a key input to photosynthesis, and elevated levels in the 1,000-1,500 ppm range can meaningfully increase growth rates in enclosed spaces. Accurate monitoring keeps supplementation in that useful range instead of wasting gas on over-injection.

How does the aspirated design help with CO2 accuracy specifically?

CO2 can settle unevenly across a room depending on ventilation, concentrating near the floor or ceiling. The aspirated design actively pulls canopy-level air across the sensor, so the reading reflects what plants are actually experiencing rather than a stratified pocket.

Can I mix this sensor with standard ClimaLINK units on the same CanopyLINK hub?

Yes, both sensor variants are compatible with the CanopyLINK's 8 channels. That lets you place CO2 sensors specifically in zones where supplementation is active while using standard ClimaLINK sensors elsewhere.
