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.
Humidity refers to the presence of water vapor in the atmosphere. It is measured in either relative terms (relative humidity) or absolute terms (dewpoint temperature). Water vapor is, as the name implies, the vapor form of water. It is totally transparent, just like the rest of the gases in the atmosphere.
