Growlink Climalink – No Co2

Growlink ClimaLINK climate sensor for aspirated canopy monitoring The ClimaLINK reads canopy air at -40 to 257°F (-40 to 125°C) ±0.18°F and 0–100% RH ±1.0%, then derives VPD on board so the values that drive transpiration arrive already calculated at the Growlink hub. Passive sensors stall in dense canopies. The aspirated head pulls a steady stream of air across the probes, which matters when leaf-height microclimates form around the housing and a static sensor ends up reading the dead spot instead of the actual canopy. Two configurations for any grow room climate sensor build GL-LINK-CLIMATE covers temp, humidity, light, and VPD; GL-LINK_CLIMATECO2 adds an NDIR 0–5000 ppm CO₂ sensor at ±3% accuracy for rooms actively dosing CO₂. Both share the same 9.25" × 4.375" × 3.75" housing with sealed filters over the intakes, which matters less in a clean propagation room than in a flowering room where overspray and root-zone dust eventually creep into exposed probes. Hang it at leaf height, run the included 5m M8 cable to the hub, and the readings feed the same Growlink OS pipeline that handles irrigation, substrate VWC, and climate setpoints. Key Features Aspirated Sensor Head: Active airflow across the probes keeps readings honest in dense canopies where passive sensors stall on stale air pockets. Built-in VPD Calculation: Vapor pressure deficit arrives pre-computed at the hub, so Growlink OS plots VPD without an extra calculation layer on the dashboard. Optional NDIR CO₂ Module: The CLIMATECO2 SKU adds 0–5000 ppm sensing at ±3% accuracy, sized for rooms running active CO₂ enrichment up to typical flowering targets. Wide Temperature Range: -40 to 257°F (-40 to 125°C) at ±0.18°F resolution covers propagation cold rooms through greenhouse summer peaks without switching probes. Sealed Filter Construction: Filters over each intake keep media dust and irrigation overspray off the sensor element across a full flowering cycle. 5m M8 Cable Included: Pre-terminated cable runs from the ClimaLINK to the Growlink hub without a custom harness or field-built connector. Growlink OS Integration: Data drops into the same dashboard, logging, and automation rules as Growlink's irrigation and substrate sensors.
