According to an embodiment of the present invention, a rain sensor comprises: a substrate; a sensing electrode formed on a first surface of the substrate; a reaction layer formed on the first surface of the substrate to embed an upper surface of the substrate and the sensing electrode; a driving unit electrically connected to the sensing electrode formed on the first surface of the substrate and processing a sensed signal delivered from the sensing electrode; and a protective layer formed to surround the driving unit, wherein the impedance value of the reaction layer based on a change of at least one between a force and a dielectric constant generated by rain changes, and the sensing electrode delivers the sensed signal related to a changed amount of the impedance value of the reaction layer to the driving unit.

    실시 예에 따른 레인 센서는, 기판; 상기 기판의 제 1 면에 형성되는 감지 전극; 상기 기판의 제 1 면위에 형성되어 상기 기판의 상면 및 상기 감지 전극을 매립하는 반응층; 상기 기판의 제 1 면에 형성된 감지 전극과 전기적으로 연결되며, 상기 감지 전극을 통해 전달되는 감지 신호를 처리하는 구동부; 및 상기 구동부를 둘러싸며 형성되는 보호층을 포함하며, 상기 반응층은, 강우 여부에 의해 발생하는 힘 및 유전 상수 중 적어도 어느 하나의 변화에 따른 임피던스 값이 변화하며, 상기 감지 전극은, 상기 반응층의 임피던스 값의 변화량에 대한 상기 감지 신호를 상기 구동부로 전달한다.
