Although "the Weather friar" has been sometimes wrongly cited as the oldest hygrometer-meteorologist in the world, [1] [3] there is a similar hygrometer, with the shape of a Capuchin friar as well, from the late 18th century, in the Museum of Arts and Crafts in Paris, built by Charles Alexandre Clair and belonging to the physics office of Jacques Charles, who would bequeath his collection of ...
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.

Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction
It was invented by Daniel Gabriel Fahrenheit (1686–1736), better known for his work in thermometry. The Nicholson hydrometer , after William Nicholson (1753-1815), is similar in design, but instead of a weighted bulb at the bottom there is a small container ("basket") into which a sample can be placed.
A hygrometer measures the relative humidity at a location, which can then be used to compute the dew point. Radiosondes directly measure most of these quantities, except for wind, which is determined by tracking the radiosonde signal with an antenna or theodolite.

Jacques Alexandre César Charles (12 November 1746 – 7 April 1823) was a French inventor, scientist, mathematician, and balloonist.Charles wrote almost nothing about mathematics, and most of what has been credited to him was due to mistaking him with another Jacques Charles (sometimes called Charles the Geometer [1]), also a member of the Paris Academy of Sciences, entering on 12 May 1785.
