Abstract: A modular water faucet, which includes a base operatively connected to a spout. The base and spout each have a cubical design and include thereon means for mounting decorative panels of various design and/or color. The modules making up the base can be stacked to any desired height, and the spouts are interchangeable with the base. The water faucet includes an automatic control system for dispensing water upon the sensing of a human body or other object near an outlet of the spout. The control system uses infrared light to detect the presence of an object. Means for differentiating the reflected light from ambient light are included. Water temperature is also sensed and compared to a preselected temperature. Water is prevented from flowing if the temperature is in excess of the preselected temperature and warnings are given in an automatic mode. Water flow will proceed if a manual mode is initiated. The control system also detects the position of the spout relative to the base.
