| 摘要 |
The invention relates to a sensor device for detecting moisture, especially precipitation and dirt, on a window (22). Said device comprises at least one emitter (12) and at least one receiver (14) for receiving the light (26) radiated from the emitters (12). The emitter (12) and receiver (14) are arranged at the corner points of an imaginary triangle or parallelogram (16). As a result, the outer dimensions (b, 1) of the sensor are reduced and the ratio of the sensitive surface area (20) to the base surface area (16) of the sensor is improved.
