Weather Station by Growlink

All-in-One SDI-12 Weather Sensor with No Moving Parts The Growlink Wireless Weather Station centers on Campbell Scientific's ClimaVUE50 — a compact digital head with no cups, no vanes, or tipping buckets. One SDI-12 line carries air temperature, RH, vapor pressure, barometric, wind, solar radiation, precipitation, and lightning back to the controller. Wind reads 0–30 m/s at ±0.3 m/s or 3%, precipitation lands at 0.017 mm resolution, and solar covers 0–1,750 W/m². Compact Outdoor SDI-12 Weather Sensor Built for Long-Term Sites Average current sits under 1 mA at 12 Vdc. The head pairs cleanly with a small solar panel and a 12 V battery for off-grid sites. A built-in tilt sensor flags mast lean that would skew wind direction or rainfall totals. Mount the head on a 1.25–2.0 in OD pole using the included V-bolt. The Growlink wireless module pushes readings to the dashboard alongside your terraLINK substrate and ESM climate channels. Key Features ClimaVUE50 SDI-12 head: Air temp, RH, vapor pressure, barometric, wind, solar, precipitation, and lightning log over one SDI-12 line. No moving parts: Sonic wind, acoustic rain, and AM-band lightning detection — nothing wears out the way cups and tipping buckets do. Wind 0–30 m/s at ±0.3 m/s or 3%: Direction reads 0–359° at ±5°, accurate enough for VPD and ET math on greenhouse vents. Precipitation at 0.017 mm resolution: Acoustic detection captures micro-events and stays accurate through driving rain to 400 mm/h. Solar 0–1,750 W/m² and barometric 500–1,100 hPa: Full-spectrum site logging for dew point, ET, and front tracking. Built-in tilt sensor: Flags mast lean that would skew wind direction or rainfall totals after a freeze cycle. <1 mA at 12 Vdc: Pairs cleanly with a small solar panel and a 12 V sealed battery for off-grid sites.
