Refrigerator with dual sensor control with adaptive algorithm
A refrigerator includes: a cabinet defining a refrigeration compartment with an opening and a door pivotally connected with the cabinet; a see-through door with an interior light for illuminating the refrigeration compartment and/or a dispenser mounted in the door or in the cabinet for dispensing water and/or ice; and a sensor unit operatively associated with the interior light and/or the dispenser, the sensor unit including at least two spaced apart sensors in operational communication with a controller, each sensor producing an output signal, the controller senses a timing difference between the output signals from the at least two sensors caused by the movement of the operator to control dispensing, and the controller establishes a calibration setting based on the output signals of the sensor where ambient changes to the output signals are differentiated from the timing difference.
