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

Track Temperature, Humidity, Light, and VPD From a Single Aspirated Sensor

The Growlink ClimaLINK Climate Sensor puts four of the most important environmental readings — temperature, humidity, light intensity, and vapor pressure deficit — into one canopy-level device. Rather than relying on a passive sensor that can sit in a pocket of stagnant air, ClimaLINK actively draws air across its sensor elements so readings reflect what plants are actually experiencing, not a stale average.

VPD is calculated automatically from the temperature and humidity readings, feeding directly into Growlink automation triggers without any extra math or middleware. Replaceable filters shield the sensor from dust and moisture in active grow spaces.

Key Features & Benefits

• Four-Parameter Monitoring: Measures temperature, relative humidity, light intensity (PPFD), and VPD from a single sensor.
• Aspirated Sensor Design: Active airflow eliminates the stagnant-air bias that affects passive sensors.
• Automatic VPD Calculation: Computes vapor pressure deficit in real time for direct use in automation triggers.
• Dust and Moisture Protection: Replaceable filters guard sensor elements against particulate buildup and humidity exposure.
• Seamless Growlink Integration: Connects via CanopyLINK or HUB to feed all parameters into Growlink OS.

Who Should Use This

Indoor cultivators and greenhouse operators who need accurate, continuous environmental data to drive VPD-based climate strategies are the direct fit for ClimaLINK, particularly operations using Growlink automation to control HVAC, dehumidifiers, or lighting in response to real-time conditions.

About Growlink

Founded in 2015, Growlink designs its ClimaLINK sensor line and broader LINKS ecosystem to give cultivators one consistent data stream across every environmental variable that matters.

Frequently Asked Questions

What parameters does the ClimaLINK monitor?

The ClimaLINK monitors temperature, relative humidity, light intensity (PPFD), and vapor pressure deficit. VPD is calculated automatically from the temperature and humidity readings rather than requiring a separate sensor.

What is an aspirated sensor design and why does it matter?

An aspirated design uses a small internal fan to actively draw air across the sensor elements, which prevents stagnant air from accumulating around them. This eliminates the measurement bias that passive sensors experience in enclosed or low-airflow spots, giving more accurate readings.

How does the ClimaLINK connect to the Growlink platform?

It connects via an M8 cable to a Growlink CanopyLINK hub or the Growlink HUB, integrating into Growlink OS for real-time monitoring and automation triggers. No direct Wi-Fi connection is needed at the sensor itself.

When should I replace the ClimaLINK filters?

Growlink recommends replacing the filters after every harvest cycle to maintain accurate readings. Replacement filters are available separately as a 2-pack (GLXCLIMALINKFIL).
