<p><P>PROBLEM TO BE SOLVED: To provide a sensor device and its fixator which reliably sense in-car internal humidity so that relative humidity measured by a sensor matches the relative humidity on windows. <P>SOLUTION: This sensor device is provided with a dew point sensor 10, having a humidity sensor element 1 and a temperature sensor 2 and where the element 1 and the sensor 2 are thermally-coupled and a surface temperature sensor 4 for determining both the internal humidity of the volume partitioned by wall, especially in-vehicle room 3, and fogging occurrence pattern of the wall, especially the inside surface on the window 5 of the in-vehicle room 3. It is proposed for this sensor device that the dew point sensor 10 is designed as to measure the air humidity and room temperature of internal volume, while the surface temperature sensor 4 is designed as to measure the surface temperature of the inside surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
