Annotation
It was shown that in a humid gas environment at a certain value of the thermal energy (temperature), the temperature coefficient of delay (TCD) of the acoustoelectronic device has a zero value. There is an interrelation between the temperature of zero value of TCD and the dew point. It was suggested that dependence of Zero value of TCD of vapor pressure be used for determination relative humidity. Advantages of this method are considered.
