Disclosed are a rain sensor for sensing vibration and an operation method thereof. According to an embodiment of the present invention, the rain sensor for sensing vibration receives a first electric signal having a first resonance frequency from a first resonance circuit connected to a sensing coil arranged to face a sensing member and be separated from the sensing member in a first direction. The rain sensor for sensing vibration receives a second electric signal having a second resonance frequency from a second resonance circuit. The rain sensor for sensing vibration generates a third electric signal having a differential frequency component corresponding to the difference between the first resonance frequency and the second resonance frequency by processing the first electric signal and the second electric signal. The rain sensor for sensing vibration also generates an output signal having the size corresponding to displacement in a first direction of the sensing member on the sensing coil and having the size corresponding to the differential frequency component. The purpose of the present invention is to provide the rain sensor and the operation method thereof, capable of accurately dividing contact of a raindrop and a change in humidity caused by dew, fog, or frost without an additional sensing unit.
