The invention discloses a resistive array sensor data feature extraction method, device and equipment and a medium, and the method comprises the steps: collecting the original gas response data of a to-be-extracted sample gas under a preset cycle index, and constructing a corresponding sensor signal curve based on the original gas response data; the signal-to-noise ratio of the sensor signal curve is calculated based on the protrusion degree of the wave crest, the width of the wave crest, the sensor original signal, the sensor noise reduction signal, the number of the wave crest and the preset cycle index in the sensor signal curve, and the sensor corresponding to the maximum value of the signal-to-noise ratio serves as a target sensor; determining a target base point time sequence from the target sensor signal, and respectively determining a sensor baseline of each sensor based on each sensor signal curve applied to the electronic nose system based on the target base point time sequence; and acquiring gas da
