Abstract: A device for measuring dew point or humidity comprises a single resonator and at least one temperature-regulating element arranged to control the temperature of the resonator by heating and/or cooling. Frequency measuring circuitry is arranged to generate signals indicative of measured frequencies of the resonator. At least one controller or processor receives the signals and determines the temperature of the resonator at which condensation (e.g., dew, frost, or condensed vapor) appears on the resonator or evaporates from the resonator according to the signals.
