description The invention discloses a device and a method for detecting water content of fresh tobacco leaves. The device comprises a detection box, a first electrode plate, a second electrode plate, a frequency measuring device and a computer, wherein the detection box is internally provided with an SAW (Surface Acoustic Wave) harmonic vibration detector and a stabilized voltage supply; the stabilized voltage supply is electrically connected with a power supply end of the SAW harmonic vibration detector; two detection ends of the SAW harmonic vibration detector are electrically connected with the first electrode plate and the second electrode plate respectively; the output end of the SAW harmonic vibration detector is electrically connected with the input end of the frequency measuring device; the output end of the frequency measuring device is electrically connected with the computer. With the method, the fresh tobacco leaves to be detected are detected through the SAW harmonic vibration detector, a characteristic valu
