The Doppler Motion Sensor Switch is a game changer for motion detection in home lighting. FCC tested and approved, the sensor emits harmless waves that can pass through thin barriers such as a cabinet or shelf panel. When motion is detected, the lighting will be triggered with a smooth brightening to full output. Install it out of sight, facing the direction where motion detection is desired, and choose how long the lighting will remain on once activated, up to four minutes.
