Ideal uses
Perfect for bathrooms where moisture buildup is common, laundry rooms with running—or vented—machines, basements prone to dampness, and other utility spaces where consistent air exchange matters. If you want a low-effort way to maintain air quality and reduce humidity-related issues, this sensor/fan control is a practical, no-fuss upgrade.
How it works
Once wired into a standard single-pole circuit, the humidity sensor continuously monitors room moisture levels. When humidity rises above the sensor’s threshold, the connected fan automatically engages to vent moist air. As the space dries, the fan turns off, delivering automatic humidity control without manual intervention.
Installation notes
Requires a 120V circuit and a compatible Decora wall plate (not included) to achieve a finished look. UL Listed for safety, with a 5A/600W load rating to cover typical residential ventilation needs. A reliable, simple upgrade for improving indoor comfort and reducing moisture-related concerns.
