Abstract
One or more techniques and/or systems are provided for detecting an object, such as a person. For example, a sensing system may comprise a sensor arrangement. The sensor arrangement may comprise a passive sensor and an active sensor. The active sensor may be placed into a sleep state (e.g., a relatively low powered state) until awakened by the passive sensor. For example, responsive to detecting a presence of an object (e.g., a nurse entering a patient's room), the passive sensor may awaken the active sensor from the sleep state to an active state for detecting motion and/or distance of the object within a detection zone to create object detection data (e.g., an indication of a hygiene opportunity for the nurse). The active sensor may transition from the active state to the sleep state responsive to a detection timeout and/or a determination that the object left the detection zone.
