The OSCxx-UOW series occupancy sensor is a low voltage occupancy sensor that controls indoor lighting. The sensor fills the room with continuous high frequency (ultrasonic) sound waves. Any movement within the sensor’s range causes a shift in the original emitted frequency. The sensor’s receiver identifies any change in frequency as motion and either turns the lights on or maintains lights on.
