<p>The present invention relates to a defog sensor unit measuring the temperature of a front glass and the inside temperature of a vehicle by clearly separating the temperatures and simultaneously accurately detecting the temperature of the front glass and the inside temperature, thereby significantly improving performance of a sensor. The defog sensor unit comprises: a hollow type case unit including a support unit wherein an adhering member is accommodated on the inner front side; a base unit connected to a lower side of the case unit, having a predetermined space portion between a PCB unit and the base unit, and having a through hole wherein the adhering member is penetrated in a side of the base unit; the PCB unit connected to the upper portion of the base unit, having a through groove wherein the adhering member is penetrated in a side of the PCB unit; a temperature sensor arranged in a flexible PCB mounted to an end portion of the support unit, sensing the temperature of the front glass of the vehicle; the adhering member inserted into an inner groove in the support unit of the case unit, pressurizing the flexible PCB to the lower direction for a position of a temperature sensor to be close to the front glass; and a temperature and humidity sensor fixated in a side of the PCB unit, detecting the temperature and the humidity of the vehicle interior.</p> |
