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

Precision Climate Monitoring at the Canopy with the Growlink ClimaLINK Sensor

The Growlink™ LINKS ClimaLINK Climate Sensor delivers real-time monitoring of temperature, humidity, light intensity, and vapor pressure deficit (VPD) directly at the canopy level, providing the critical environmental data needed to drive precision climate control in indoor growing environments. Its aspirated design actively circulates air across the sensor elements, eliminating the stagnant air pockets that cause temperature and humidity readings to drift — ensuring your automation decisions are based on accurate, representative measurements.

Built-in VPD calculation gives cultivators immediate access to one of the most important physiological indicators in plant management, allowing for direct integration with Growlink's automation triggers without additional processing. Protective filters shield the sensor from dust and moisture in high-humidity grow environments, and the ClimaLINK's durable construction is engineered for continuous deployment in greenhouse and indoor cultivation settings. Made in the USA.

Key Features & Benefits

• Four-parameter monitoring — measures temperature, relative humidity, light intensity (PPFD), and VPD from a single sensor for comprehensive climate insight.
• Aspirated sensor design — active airflow across sensor elements eliminates stagnant air bias, delivering more accurate and consistent readings than passive sensors.
• Automatic VPD calculation — computes vapor pressure deficit in real time, enabling direct VPD-based automation triggers within the Growlink platform.
• Dust and moisture protection — replaceable filters guard sensor elements against particulate buildup and humidity exposure in active grow environments.
• Seamless Growlink integration — connects via CanopyLINK or HUB to deliver all parameters into Growlink OS for centralized monitoring and climate automation.
• Made in the USA — built to professional cultivation standards for long-term reliability in demanding indoor and greenhouse environments.

Who Should Use the Growlink ClimaLINK Climate Sensor

The ClimaLINK is ideal for indoor cultivators and greenhouse operators who require accurate, continuous environmental data to support VPD-driven climate management strategies. It is particularly valuable in operations using Growlink's automation platform to control HVAC systems, dehumidifiers, and lighting in response to real-time environmental conditions — where sensor accuracy directly determines the quality of automated climate responses.

VPD-Driven Climate Optimization

Vapor pressure deficit is the cornerstone of modern indoor crop management, governing transpiration rate, nutrient uptake efficiency, and susceptibility to disease pressure. The ClimaLINK's integrated VPD calculation brings this critical parameter into your Growlink automation workflow without additional sensors or manual calculation — enabling your climate control systems to respond dynamically to actual plant-zone conditions rather than setpoints derived from remote or passive sensors.

Frequently Asked Questions

What parameters does the ClimaLINK monitor?

The ClimaLINK monitors temperature, relative humidity, light intensity (PPFD), and vapor pressure deficit (VPD). VPD is calculated automatically from temperature and humidity readings.

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, preventing stagnant air from accumulating around the sensor. This eliminates the measurement bias that passive sensors experience in enclosed or low-airflow environments, resulting in more accurate readings.

How does the ClimaLINK connect to the Growlink platform?

The ClimaLINK connects to Growlink via a CanopyLINK hub or the Growlink HUB using an M8 cable. It integrates into Growlink OS for real-time monitoring and automation triggers.

How often should I replace the ClimaLINK filters?

Growlink recommends replacing the filters after every harvest cycle. Replacement filters are available separately (GLXCLIMALINKFIL — 2-pack).

Can I use multiple ClimaLINK sensors in the same grow space?

Yes. Multiple ClimaLINK sensors can be deployed across different zones and connected to a single CanopyLINK (up to 8 channels) or additional CanopyLINK units for larger operations.
