(Wikipedia excerpt: ..."...A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor.[1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can be used to indicate the humidity. Modern electronic devices use the temperature of condensation (called the dew point), or they sense changes in electrical capacitance or resistance.

The maximum amount of water vapor that can be present in a given volume of air (saturation) varies greatly by temperature; cold air can contain a lower mass of water per unit volume than hot air. Thus a change in the temperature can change the humidity.....")
