Microwave Motion Detection System and Lighting Applications
A microwave motion detection system and lighting applications are disclosed. Time slicing and Pulse Width Modulation (PWM) techniques are used to improve efficiency in microwave motion detection sensors. Systems employing motion detection may control the detection of irrelevant motion with shielding and changing the power of the microwave motion detection sensor. Distance-based zones may be designated, and motion may be detected in particular zones. Different device operation may be performed based on motion detection in different zones. In lighting applications, varying device operation may include varying the direction, amount, or duration of light output. Device operation, when motion is detected, may also be based on the time of day, user preference, and power status parameters.
