This Humidity Sensor and Fan Control detects excess humidity in a room and automatically activates the ventilation fan to reduce excess condensation. This helps to lessen the appearance of mold and mildew and provides a more comfortable environment.

The sensor uses state-of-the-art technology to continuously monitor the air in a room and automatically turn on the ventilation fan when it detects a rise in humidity. The device features easily adjustable settings for sensor sensitivity, humidity level and automatic time out which can be set to meet the specific ventilation needs of a room.
