Illustrated on this slide are some of the common reasons why it is important to monitor and control humidity and temperature. These reasons include but are not limited to; the prevention of the formation of molds and fungus that cause diseases, to maintain a certain product fresh in a storage room where fruits and vegetables are stored and/or ripening, and monitor the environment for fermentation, like in beer or winemaking. It is also used for incubation of eggs, to ensure the maintenance of good quality in some special personal collections like paintings, guitars, or clothing; and, to give a healthy environment, for example, maintaining a good air quality to avoid dryness on skin and eyes that cause discomfort and breathing-related illness like asthma.
