LEVITON OSC20-U0W Occupancy Sensor Ultrasonic 24 VDC, White

The OSCxx-U is a low voltage occupancy sensor that controls indoor lighting. The sensor fills the room with continuous reflective 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. Self Adjusting: An internal microprocessor automatically analyzes, evaluates and adjusts time delay and U/S settings for maximum energy savings. Walk-Through: Provides increased energy savings by decreasing the time delay to 2.5min when someone momentarily walks through the monitored space.
