Abstract:

A fluid delivery apparatus includes a spout, an active sensor, and a passive sensor. The active sensor is configured to detect the presence of a user adjacent the spout when enabled. The passive sensor is configured to define a sensing field in an area near the spout and also to detect a presence of a user. A controller is coupled to the passive sensor and the active sensor. The controller is programmed to detect the presence of a user in the sensing field based on an output signal from the active sensor in response to detecting the presence of the user in the sensing field with the passive sensor, thereby reducing the amount of power used by the active sensor.
