The invention discloses an infrared induction signal de-jitter filtering method and system and application, and the method comprises the steps: obtaining the signal intensity, and obtaining the intensity of an infrared induction signal in real time; increment judgment: when the intensity of the infrared induction signal reaches a preset range, judging whether the intensity of the infrared induction signal in preset time is continuously increased or attenuated; and instruction output: when the infrared sensing signal is continuously increased or attenuated, outputting an approaching or leaving signal instruction. According to the scheme of the invention, whether an object approaches or leaves away can be accurately judged, the sensing precision of the sensor is improved, and the occurrence of wrong judgment of the sensor is reduced.
