Abstract
A method for saving power consumption of a position sensitive detector used in a smart bathroom product includes changing infrared light emitting strength modes depending on the received strength of reflected infrared light. If the emitting mode is already the strongest, and the strength of the reflected infrared light received back from a reflecting object is weak, the method includes conducting multiple subsequent emissions and averaging the returns to estimate a distance to the infrared light reflecting object.
