Sensor for determining the interior humidity and fogging up tendency and fastening device of the sensor
First Claim
1. Sensor for determining an interior humidity or an interior dew point of an interior volume delimited by a wall, and a fogging up tendency of an inner surface of the wall, said sensor comprising:
- a printed board;
a dew point sensor, mounted to the printed board, having a humidity sensor element measuring air humidity of the interior volume;
a temperature sensor, mounted to the printed board, measuring room temperature of the interior volume; and
a surface temperature sensor measuring a temperature of the inner surface, said printed board having an elongated basis shape consisting of a protruding end and a support surface, the surface temperature sensor is mounted to the protruding end and the dew point sensor is disposed on the support surface.
