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.
In 1783, the first hair hygrometer is demonstrated by Horace-Bénédict de Saussure. In 1806, Francis Beaufort introduced his system for classifying wind speeds . [ 4 ] The April 1960 launch of the first successful weather satellite, TIROS-1 , marked the beginning of the age where weather information became available globally.
With the inventions of the hygrometer and thermometer, the theories of combining the two began to emerge during the sixteenth and seventeenth centuries. In 1818, a German inventor, Ernst Ferdinand August (1795-1870), patented the term “psychrometer”, from the Greek language meaning “cold measure”.
TV Tropes was founded in 2004 by a programmer under the pseudonym "Fast Eddie." He described himself as having become interested in the conventions of genre fiction while studying at MIT in the 1970s and after browsing Internet forums in the 1990s. [17]
Flanderization is a widespread phenomenon in serialized fiction. In its originating show of The Simpsons, it has been discussed both in the context of Ned Flanders and as relating to other characters; Lisa Simpson has been discussed as a classic example of the phenomenon, having, debatably, been even more Flanderized than Flanders himself.

A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.
For those not familiar, TV Tropes is a wiki that lists plot devices, tropes, and the like in all manner of fiction. However, the fact that it's a wiki is where the similarity to Wikipedia ends. While Wikipedia does have articles on various plot devices and tropes, the intent is to give an encyclopedic outlook on how these elements are perceived.
The original company, Michell Instruments Ltd, was formed in 1974 in Cambridge, England, by Andrew Michell.In co-operation with scientists at Cambridge University, Michell developed a novel aluminium oxide dew-point sensor based on the thin-film capacitance principle originally proposed by Dr A C Jason et al. at the Torry Research Institute, Aberdeen, UK in the 1950s.
