File Size: 2MB. Humidity measurement is based on the change of physical propert ies due to moisture. Moisture Moisture measurement method s are based on variation in.
A measurement model then converts such a quantity value into the corresponding value of the measurand. There are many types of measurement, and therefore many measurement models.
A simple measurement model (for example, for a weighing scale, where the mass is proportional to the extension of the spring) might be sufficient for everyday use.

Smith, in Encyclopedia of Atmospheric Sciences (Second Edition), Principle of Operation. Capacitive humidity sensors relate measurements of the capacitance between two charged plates to the ambient water vapor mixing ratio, through the measurement of relative humidity (RH).
RH is defined as the vapor pressure of water in the air sample (p H 2 O samp). reliable and accurate humidity measurement, even in environments with % relative humidity (RH) where wet humidity sensors are unable to measure. In high relative humidity (over 90% RH) all objects, including humidity sensors, are likely to be at a temperature close to saturation.
In such an environment the vapor pressure gradient is insufficient. Specific humidity measures the weight of water vapor per unit weight of air. This unit of measurement, expressed as grams of water vapor per kilogram of air (g/kg), does not change depending on temperature or atmospheric pressure.
Specific humidity as a unit of measurement is more useful than absolute humidity.measurement techniques, the most commonly used units for humidity measurement are Relative Humidity (RH), Dew/Frost point (D/F PT) and Parts Per Million (PPM).2 Relative Humidity (RH) is the ratio of the partial pressure of water vapor present in a gas to the saturation vapor pressure of the gas at a given temperature.
RH is a func-File Size: KB. Humidity sensors based on thin film and field-effect transistors, heterojunctions, flexible substrates, and integrated humidity sensors are also discussed in this volume. Great attention is also paid to the consideration of conventional devices, which were used for the measurement of humidity for several : Ghenadii Korotcenkov.
