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

Complete Five-Parameter Climate Monitoring with CO2 — The Growlink ClimaLINK Sensor with CO2

The Growlink™ LINKS ClimaLINK Climate Sensor with CO₂ builds on the proven ClimaLINK platform by adding real-time CO₂ monitoring to its comprehensive environmental data suite. Measuring temperature, humidity, light intensity, VPD, and carbon dioxide levels simultaneously, this sensor delivers everything needed to optimize climate control and CO₂ supplementation strategies in indoor growing environments from a single, elegantly integrated device.

Like the standard ClimaLINK, this sensor features an aspirated design that actively circulates air across sensor elements for accurate, drift-free readings — critical when monitoring CO₂ levels that can stratify unevenly across a grow canopy. Built-in VPD calculation and protective dust and moisture filters round out a sensor engineered for continuous, reliable deployment in professional cultivation settings. Made in the USA.

Key Features & Benefits

• Five-parameter monitoring — measures temperature, relative humidity, light intensity (PPFD), VPD, and CO₂ from a single sensor for the most complete climate picture available.
• Real-time CO₂ monitoring — tracks carbon dioxide concentrations to support precise CO₂ supplementation management and ensure enrichment stays within optimal ranges.
• Aspirated sensor design — active airflow across sensor elements eliminates stagnant air bias, critical for accurate CO₂ readings at the grow canopy.
• Automatic VPD calculation — computes vapor pressure deficit in real time for direct integration with Growlink climate automation triggers.
• Dust and moisture protection — replaceable filters protect all sensor elements from particulate buildup and humidity exposure.
• Seamless Growlink integration — connects via CanopyLINK or HUB to deliver all five parameters into Growlink OS for unified monitoring and automation.
• Made in the USA — engineered to professional cultivation standards for long-term performance in demanding environments.

Who Should Use the Growlink ClimaLINK Sensor with CO2

This sensor is the preferred choice for cultivators running active CO₂ supplementation programs who need to monitor enrichment levels alongside temperature, humidity, VPD, and light in a single device. Operations using Growlink automation to control CO₂ injection systems will benefit significantly from having CO₂ data integrated directly into the same sensor stream that drives their broader climate management decisions.

CO2 Management and VPD-Driven Climate Optimization

Effective CO₂ supplementation depends on accurate, real-time concentration data — both to confirm that enrichment is reaching target levels and to prevent wasteful over-supplementation. When CO₂ monitoring is combined with temperature, humidity, VPD, and light data in a single aspirated sensor, cultivators gain a complete picture of the photosynthetic environment at the canopy. This enables tightly coordinated automation responses where CO₂ injection, HVAC, and lighting systems work in concert to maintain peak growing conditions throughout each photoperiod.

Frequently Asked Questions

What is the difference between the ClimaLINK and the ClimaLINK with CO2?

The standard ClimaLINK monitors temperature, humidity, light (PPFD), and VPD. The ClimaLINK with CO₂ adds a fifth parameter — real-time carbon dioxide concentration monitoring — making it the better choice for operations using CO₂ supplementation.

Why is CO2 monitoring important in indoor growing environments?

CO₂ is a key driver of photosynthesis. Elevated CO₂ levels (typically 1,000-1,500 ppm) can significantly increase growth rates and yields in enclosed environments. Accurate monitoring ensures supplementation stays within the optimal range and prevents wasteful over-injection.

Does the aspirated design help with CO2 accuracy?

Yes. CO₂ can stratify in enclosed spaces — concentrating near the floor or ceiling depending on ventilation. The aspirated design actively draws canopy-level air across the sensor, ensuring readings represent the CO₂ environment plants are actually experiencing.

How does the ClimaLINK with CO2 connect to the Growlink platform?

It connects via an M8 cable to a Growlink CanopyLINK hub or the Growlink HUB, integrating all five parameters into Growlink OS for real-time monitoring, dashboards, and automation triggers.

Can I mix ClimaLINK and ClimaLINK CO2 sensors in the same CanopyLINK hub?

Yes. Both sensor variants are compatible with the CanopyLINK's 8 channels, allowing you to place CO₂ sensors in zones where supplementation is active while using standard ClimaLINK sensors in other zones.
