Occupancy Sensor Light Switch automatically turns lights and motors on and off according to the motion detected in the room. Equipped with ambient light detection, you can customize your sensor to detect daylight so lights don't turn on with enough natural light in your room. The sensor detects motion in areas up to 900 sq. ft. and up to 35 ft. from the sensor, ideal for porch, closet, garage, hallway, stairs, basement, pantry and laundry room, etc. Exquisite matte finish and frameless design looks best with today's decors.
