Abstract

A sensor arrangement comprises a dew point sensor for measuring the dew point characteristic in a room, and a temperature sensor for measuring the temperature characteristic on a wall surface of the room, means being provided for evaluating and/or storing the measured dew point characteristic and the measured wall surface temperature characteristic.

Claims

1. Sensor arrangement for determining mould-forming tendency of a wall of a room, the arrangement comprising:

a dew point sensor for measuring a dew point characteristic in the room;

a temperature sensor for measuring a temperature characteristic on a wall surface of the room;

means for evaluating and/or storing the measured dew point characteristic and the measured wall surface temperature characteristic; and

an evaluation unit for storing a mould-forming tendency indicator in a storage module when the wall temperature characteristic falls below a dew point temperature of a dew point of the air in an interior volume space of the room or a predetermined temperature limit.

2. Sensor arrangement according to claim 1, wherein the evaluation unit is operative for controlling a heating system when the dew point temperature falls below the dew point temperature.

3. Sensor arrangement according to claim 1, wherein the evaluation unit is operative for emitting an alarm signal when the dew point temperature falls below a mounting site temperature sensor.

4. Sensor arrangement according to claim 1, wherein the dew point sensor is arranged in a housing, and the sensor arrangement further comprises a data transfer interface having a wireless communication interface, and/or a connector interface, disposed on the housing.

5. Sensor arrangement according to claim 4, wherein the housing is formed at least partly by a moisture-permeable membrane or air passage holes.

6. Sensor arrangement according to claim 1, further comprising adhesives for securing the temperature sensor to the wall surface.

7. Building management control center having at least one sensor arrangement according to claim 1, further comprising data acceptance means for accepting the measured wall temperature characteristics and the measured air humidity characteristics of the sensor arrangement and output means for outputting a mould-forming tendency indicator.

8. Use of the sensor arrangement according to claim 1 for determining a mould-forming tendency in a room of a building.
