Description
Precision climate monitoring at canopy level for smarter environmental control.
ClimaLINK is Growlink's advanced climate sensor, delivering accurate, real-time monitoring of temperature, humidity, light, and optional CO2. Designed to operate at canopy level, it gives growers a true picture of the conditions that directly impact plant performance.
With built-in VPD calculation and an aspirated sensor design, ClimaLINK ensures reliable data for optimising transpiration, growth rates, and resource efficiency. All readings are fed directly into Growlink OS, enabling automated control, alerts, and detailed environmental tracking.
Important Compatibility Information
This sensor requires a CanopyLINK 8-Port Sensor Hub to operate.
ClimaLINK does not function as a standalone device. It must be connected to a CanopyLINK hub to transmit data to Growlink OS.
If you do not already have a CanopyLINK installed, please add one below to complete your setup.
Key Features
- Accurate Climate Monitoring: Measures temperature, humidity, light, and optional CO2 for precise environmental control.
- VPD Calculation: Automatically calculates vapor pressure deficit to support healthy transpiration and growth.
- Aspirated Sensor Design: Actively circulates air around the sensor for consistent, reliable readings.
- Rugged Construction: Built with protective filters to withstand dust, moisture, and demanding grow environments.
- Growlink OS Integration: Enables automation, alerts, and data-driven decision making from one central platform.

Part of the Growlink LINKS Ecosystem
LINKS is Growlink's modular grow-room hardware system: small, purpose-built devices that each do one job well, and click together into a whole-facility control network. ClimaLINK plugs into canopyLINK to add temperature, humidity, light, and CO2 data into the same feed as your substrate sensors, all landing in Growlink OS. Every LINKS device can run wirelessly on its own over Wi-Fi, but connecting canopyLINK to the HUB over a wired RJ-45 connection unlocks whole-room automation, longer signal range, and the ability for the HUB to power and enable additional LINKS hardware across the facility.

"Run cultivation from a system that learns."
Every ClimaLINK connects into Growlink OS, the cultivation management portal that turns your best irrigation practices into living Blueprints — standardised schedules and automation logic you can roll out across every room. Growlink OS includes Nova, Growlink's built-in AI, which compares performance across rooms, flags deviations from plan, and answers questions about crop performance without you having to dig through spreadsheets.
