Dual technology motion sensor MultiTechnology occupancy motion sensor switch captures very fine motion such as typing or reading to turn ON OFF the load automatically.This switch allows users to customize the triggering mode and sensitivity level according to their need for fine motion. The dual tech motion sensor integration of passive infrared PIR sensor switch and ultrasonic sensor switch technology into one motion sensor switch improves the sensors triggering accuracy and sensitivity with significantly less false triggers. When the sensor switch load is set to be triggered on when both PIR and ultrasonic sensors detect the presence of occupants, users enjoy the most precise lighting control with the least falseon and falseoff. In addition to options between Auto ON Auto OFF and Manual ON Auto OFF, MWOS always ranks the best choice for its user friendly / easy installation options including 4 trigger modes, 8 timeout, walkthrough mode, sensitivity with PIR and sensitivity with ultrasound sensor and 4 adjustable daily light range.Set the triggering condition among when either PIR sensor or Ultrasonic Sensor detects motion, only PIR sensor detects motion, only Ultrasound sensor detects motion, or both PIR and Ultrasonic sensor detect motion. This occupancy sensor wall switch features 8 AUTO OFF timeout settings: 5sec test, 30 seconds, 5, 10, 15, 20, 25 and 30 minutes. The light control switch allows users to enable or disable WalkThrough Timeout Mode: A walkthrough mode can automatically turn lights off after only 3 minutes if no activity is detected after 30 seconds following an occupancy detection. Users have 4 options to choose the day light saving level. With light level sensor in MWOS sensor switch, the load will be kept OFF even when motion is detected if the natural light is sufficient according to your light level setting. MWOS, under OCC occupancy sensor mode will turn on light when motion is detected.
