A humidity monitoring device is called a hygrometer. Hygrometers may be designed for indoor or outdoor humidity monitoring use (or both). Below is a summary of the types of hygrometers available for measuring humidity. Analog hygrometers use a moisture-sensitive material that is attached to a coil spring.
Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.
