摘要： The present invention discloses a method for saving power consumption of a position sensitive detector used in a smart bathroom product. An infrared light emitting device included in the position sensitive detector has infrared light emitting modes of at least two strengths. The position sensitive detector determines the emitting strength to be adopted by the infrared light emitting device at the time of next infrared light emission based on the comparison between the strength of the reflected infrared signal received by the infrared light receiving device and a preset value set in the position sensitive detector. Thus, by switching between different emitting strength modes, the infrared light emitting device is made to use an emitting mode with a weak strength in the case that no one is using the position sensitive detector, thereby effectively decreasing the power consumption of the position sensitive detector in its operation.

摘要： 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.
