Abstract:
1. A measuring device for detecting a humidity and temperature of a window surface, comprising: at least one moisture sensor and at least one temperature sensor placed on the window surface; an evaluation unit connected downstream from the moisture and temperature sensors, an oscillator functionally coupled to the at least one moisture sensor and the at least one temperature sensor, wherein the oscillator receives an input signal from the at least one moisture sensor and an input signal from the at least one temperature sensor; and a signal converting and linking unit placed between the moisture and temperature sensors and the evaluation unit, wherein the signal converting and linking unit comprises the oscillator; wherein when the temperature sensor detects a change in a temperature of the window surface or the moisture sensor detects a change in a moisture of the window surface, a frequency of the oscillator included in the signal and converting unit is changed.
