TopGreener Humidity Sensor Switch for Ventilation Fan, Bath Fan Control - White, With Wall Plate (3-Pack) TDHS5-WWP3P

The TOPGREENER TDHS5-W is a humidity sensor switch that automatically controls the ventilation fan to reduce humidity and moisture in the air. Equipped with a humidity sensor, you no longer must keep your bathroom fan running all day after a shower to get rid of the condensation in the air! The humidity sensor works by detecting moisture in the air to automatically turn the ventilation fan on or off based on the moisture level. The ventilation fan will continue to operate for 30 minutes or until the humidity in the room has reduced. Perfect for bathrooms, laundry rooms, spas, or any other room with high humidity levels, the TDHS5-W will help make your space more comfortable and energy-efficient. A Neutral Wire is required for installation.
