Abstract

A mirror reflection processing method for a position sensitive detector device in intelligent bathroom products. The infrared emitter in the position sensitive detector device is provided with two infrared emitting intensity modes. The position sensitive detector device determines whether to consider that no signal is collected in current collection according to the result of comparison between the reflected infrared signal intensity received by the infrared receiver and the preset value therein, thereby overcoming the mis-operation of the position sensitive detector device when being opposite to objects with relatively high reflectivity, and making the position sensitive detector device even more widely applied.
