The Leviton smart sensor uses passive infrared (PIR) detection technology to monitor a room for occupancy using a segmented, tamper resistant lens. When a person passes in or out of a sensor zone, the sensor detects motion and switches the lights on. The lights will remain on as long as an occupant is moving through the sensor zones. The ODS15-Ixx 's vacancy mode features a manual on/auto-off for installations where manual on switching is required for energy code applications. Configuration of ODS15-Ixx is made using the Leviton Smart Sensor App from a smartphone or other Bluetooth® enabled Android or iOS device.
