Occupancy sensors are heavily dependent on two technologies - the ultrasonic motion and the passive infrared PIR sensing technology. Ultrasonic motion detection is highly sensitive to small movements in large areas, while passive infrared sensing ensures superior immunity to false triggers from vibrations, inanimate objects, or movement in an adjacent corridor. Moreover, the ultrasonic motion detection can be turned on for Side A, Side B, or both sides of the occupancy sensor to avoid false occupancy readings when the sensor is facing a hallway or doorway.
