Leviton DHS05-1LT Humidity Sensor Switch for Bathroom Exhaust Fan – Light Almond

Smart humidity-based ventilation

Meet the Leviton Decora humidity sensor and fan control, a single-pole device that automatically manages bathroom airflow by responding to moisture levels. With a ¼ HP motor rating, it supports common lighting loads such as LED/CFL up to 300W and incandescent/halogen up to 600W, giving you flexible control without compromising on performance. Designed for installation with or without a neutral wire, it also lets line and load wires be interchanged to fit your wiring layout. The wallplate is sold separately to help you tailor the finish to your space. This sensor and switch combination aligns with current California Title 24, CALGREEN, and ASHRAE 62.2 requirements, offering a thoughtful approach to indoor air quality within existing electrical setups.

Real-life versatility

Imagine post-shower comfort: the fan engages automatically as moisture rises, helping to reduce lingering steam and prevent foggy mirrors. In basements or laundry rooms, the sensor can react to rising humidity after use, supporting continuous air movement. The device supports a robust range of loads and is designed to work with common bathroom fixtures while preserving the look of a standard switch.

Note: the wallplate is sold separately, and the device’s compliance features reflect standards for indoor air quality and ventilation requirements rather than guarantees—results depend on your specific setup, ducting, and climate.
