Intelligent 0-10V fan control with onboard PID algorithms and a Swiss-made Sensirion sensor. Set your target — temperature, humidity, or VPD — and walk away.
Runs fully independent once configured. No internet required. No cloud dependency. As long as it has power, it controls your fans.
Encrypted SMS and telephone voice alerts when parameters exceed your thresholds.
This isn't a dumb relay that turns fans on and off. It's a complete climate control system with its own processor running PID control algorithms — the same mathematics used in industrial process control, HVAC systems, and scientific equipment.
Configure your target setpoint — temperature, humidity, or VPD — and the controller continuously adjusts fan speed to maintain it. Not hunting. Not overshooting. Smooth, proportional control that converges on your target and holds it there.
Once configured, the controller runs entirely on its own CPU. Lose your internet connection. Lose your phone. The controller doesn't care. As long as it has power, it controls your fans.
Set a target temperature and the controller modulates fan speed to maintain it — faster when too hot, slower when at setpoint
Target a specific RH percentage — the controller increases ventilation to remove moisture or reduces it to retain humidity
The gold standard for plant transpiration. Controller calculates VPD from temp and humidity, then maintains your target deficit
Set hard boundaries — minimum and maximum fan speeds, emergency thresholds, and fail-safe behaviors
4,096 discrete speed levels — smooth, precise control without stepping or hunting
Industry-standard control voltage for EC fans and variable speed drives
DAC calibration stored in dedicated EEPROM. All settings and state retained in high-quality, long-life flash memory on the microcontroller.
Standard USB power — any phone charger works as a replacement
The quality of your fan control is only as good as the signal driving it. We use an off-board 12-bit DAC — a dedicated digital-to-analog converter that outputs a clean, precise 0-10V signal.
12-bit resolution gives you 4,096 discrete fan speed levels. That's enough granularity for the PID algorithm to make tiny adjustments without visible stepping — your fans ramp smoothly up and down as conditions change.
DAC calibration is stored in dedicated EEPROM, while all settings and operational state live in high-quality flash memory on the microcontroller — non-volatile storage that survives power loss indefinitely. Lose power, regain power, and the controller resumes exactly where it left off. No reconfiguration required.
Every fan controller ships with a Swiss-made Sensirion temperature and humidity sensor. Deploy it however suits your setup.
Sensirion sensors are the industry standard for precision environmental measurement — designed and manufactured in Switzerland, trusted in medical devices, cleanrooms, and laboratory equipment. Accurate readings mean accurate control.
The controller reports its state every five seconds — current fan speed, temperature, humidity, VPD, and setpoint status. All of it logged automatically as historical graphical data.
The server retains one month of aggregated data — enough to see trends, spot problems, and verify that your climate control is actually working as expected.
Want longer records? Our app can take daily snapshots of real-time data, building up months, years, or even decades of environmental history. Track seasonal patterns. Compare runs. Build institutional knowledge about your grow.
No subscription required. Historical data included free with every device.
The display model includes a capacitive touchscreen showing real-time readings, current fan speed, and setpoint status. Adjust targets, view graphs, and monitor your climate at a glance.
Or skip the screen entirely and use our web interface or mobile app. The headless unit is functionally identical — the display is purely a convenience for on-site interaction.
All configurations available with 2 week lead time. Shipping worldwide.
