The invention relates to a range hood smoke sensing automatic adjusting gear adjusting method. An infrared sensor module is arranged in the range hood, the infrared sensor module comprises an infraredemission tube, an infrared receiving tube and an infrared compensation tube, the range hood smoke sensing automatic adjusting gear adjusting method comprises the following steps that a, self-calibration is carried out on the infrared sensor module; b, the oil smoke is monitored and collected to obtain all sampling data; c, whether the sampling data is suddenly changed or not is judged, and if yes, the step a is executed; if not, the step d is executed; d, the sampling data are processed and calculated to obtain the smoke quantity data; e, the smoke volume data is compared with the gear thresholds, and the range hood is controlled to perform gear adjustment; and f, after the detection period, and the step b is executed. Compared with the prior art, the method can be used for adjusting thesuction gear of the range
