VIVOSUN Humidity Controller 1200W Dual-Stage | Dual LED Displays for Greenhouses & Grow Tents

The VIVOSUN Humidity Controller is a compact, reliable companion for environments that demand steady moisture. With dual-relay outputs, it can run a humidifier and a dehumidifier in tandem. Set a target humidity and a differential, and watch the unit switch automatically between humidification and dehumidification to keep the air comfortable and stable.

Key design features that matter

Visibility and simplicity go hand in hand here. Large dual LED screens display both the measured humidity and your set point in real time. A plug-and-play design, three control buttons, and a 5.9 ft power cord make setup flexible, whether you mount it on a wall or suspend it from a shelf.

• Reliable safety alarms for high/low humidity and sensor faults, plus compressor delay protection to shield your project and devices.
• Rugged 20A relay and 16 AWG power cord support dependable operation with reduced heat buildup.

The controller's sensor is ultra-sharp, with a useful range from 5% to 99% RH and an accuracy of ±3% RH. A calibration function supports long-term accuracy without complicated recalibration procedures.

Versatility in action

With a 1200W maximum output, it works with most AC100-240V humidifiers, dehumidifiers, fans, and ventilation units. This makes it suitable for greenhouses, grow tents, mushroom cultivation, incubation chambers, reptile terrariums, germination areas, and even home-brewing setups.

• Automates routine adjustments, helping you maintain consistent environmental conditions with less guesswork.
• Supports energy-aware operation by switching modes only when needed, potentially saving electricity.

Note: while the controller can help stabilize humidity, results depend on proper sensor placement and compatible equipment. Treat this tool as a possible aid toward your goals rather than a guarantee.
