The present invention relates to a raindrop sensor with an improved detection function. According to the present invention, the raindrop sensor with the improved detection function includes: an electrode sensor unit generating an open/short-based switching signal by a raindrop falling between first and second electrode plates by including the first electrode plate, which is formed to be inclined downward and has an area where the raindrop firstly comes into contact, and the second electrode plate which is separated at fixed intervals from a lower end of the first electrode, wherein the raindrop falling from the first electrode plate is secondly in contact with the second electrode plate; and a control unit including a rainfall amount database and a rainfall amount calculation unit. The rainfall amount database stores rainfall amount information according to short-state time and an occurrence number of the switching signal. The rainfall amount calculation unit calculates the rainfall amount by comparing the switching signal and the rainfall amount database. According to the present invention, the raindrop sensor with the improved detection function can rapidly drop the raindrop to the second electrode plate by using a downward inclination structure of the first electrode plate, thereby improving a raindrop sensing force and reducing residue from a foreign substance.
본 발명에 따른 감지 기능을 향상한 우적 감지 센서는, 하방 경사진 것으로서 물방울이 1차 접촉하는 영역을 가진 제 1 전극판과, 상기 제 1 전극의 하단과 일정 간격 이격된 것으로 상기 제 1 전극판에서 낙하하는 물방울이 2차 접촉하는 제 2 전극판을 포함하여 상기 제 1,2 전극판 사이로 낙하하는 물방울에 의해 open/short 기반의 스위칭 신호를 발생하는 전극 센서부; 상기 스위칭 신호의 발생 횟수와 short 상태 시간에 따른 강수량 정보를 저장한 강수량 데이터베이스와, 상기 스위칭 신호와 상기 강수량 데이터베이스를 비교하여 강수량을 산출하는 강수량 산출부를 포함한 제어부;를 포함하는 것을 특징으로 한다. 본 발명에 따른 감지 기능을 향상한 우적 감지 센서에 의하면, 제 1 전극판의 하방 경사 구조로 신속하게 물방울을 제 2 전극판으로 낙하할 수 있어 우적 감지력을 향상하면서 이물질의 잔류 여지를 줄일 수 있는 효과를 가진다.
