The Akicon humidity sensor switch automatically monitors bathroom moisture, activating the exhaust fan when levels exceed your preset threshold and shutting it off 5 minutes after returning to normal. The integrated motion-activated wall plate detects movement in low light, turning on the night light for safe, hands-free navigation in bathrooms and hallways, with selectable 2/5-minute auto-off to save energy. It features customizable timer settings (5/15/30/45/60 minutes) for post-shower ventilation and 5 adjustable humidity levels (90%/80%/70%/60%/50%) to match your space. This all-in-one unit controls one exhaust fan and two lights, compatible with most bathroom fans, ideal for bathrooms, laundry rooms, and basements. Requiring a neutral wire, it installs easily with step-by-step instructions, backed by a 3-year limited warranty for lasting peace of mind.
