The present invention relates to an automatic defog sensor unit, which is configured to indirectly detect the temperature of front glass of a vehicle by using a thermally conductive pad, which reduces cost by reducing the number of components, which is easily assembled by having a simple structure, and which has improved detection efficiency. The automatic defog sensor unit comprises: a PCB unit, of which a front end part protrudes toward a front side of a PCB, wherein a first temperature detection element detecting the temperature of the front glass of the vehicle is installed in the front end part; and a thermal conductive pad unit inserted and fixated to surround the first temperature detection element to the front end part of the PCB unit and coming in contact with a surface of the front glass of the vehicle to transmit the heat of the outdoor air at the outdoor air temperature to the first temperature detection element.

    본 발명은 열전도성 패드(Thermal pad)를 이용하여 차량 전면유리 온도를 간접적으로 감지할 있도록 구성하되, 부품수 축소에 따른 원가절감과 구조가 간단하며 조립이 용이하고 감지 효율이 향상되도록 한 오토 디포그 센서 유닛에 관한 것으로, PCB의 전방으로 선단부가 돌출 형성되고 상기 선단부에는 차량의 전면유리 온도를 감지하는 제1온도감지소자가 설치되는 PCB부; 및 상기 PCB부의 선단부에 제1온도감지소자를 감싸도록 끼움 고정되고 차량 전면유리 표면과 접촉되어 외기온도를 상기 제1온도감지소자로 열전달하여 주는 열전도성패드부를 포함하는 것을 특징으로 한다.
