A humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. A typical humidistat is usually included with portable humidifiers or dehumidifiers. It can also be included with combined air cleaner or humidifier units to control a home's humidity level or any other indoor space.
Humidity indicates the likelihood for precipitation, dew, or fogto be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.

v. t. e. A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much water vapor it contains. [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.
Water activity is the thermodynamic activity of water as solvent and the relative humidity of the surrounding air after equilibration. As temperature increases, aw typically increases, except in some products with crystalline salt or sugar. Water migrates from areas of high aw to areas of low aw.
Steve is a player character from the 2011 sandbox video game Minecraft. Created by Swedish video game developer Markus "Notch" Persson and introduced in the 2009 Java-based version, Steve is the first of nine default player character skins available for players of contemporary versions of Minecraft.

Desiccators are sealable enclosures containing desiccants used for preserving moisture -sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity. The contents of desiccators are exposed to atmospheric moisture whenever the ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
