This picture of two thermometers and a barometer was
published in 1815.
Hygrometers measure humidity (This
sketch of one is from 1688.)
Anemometers measure wind speed
(This photograph was taken in 1899.)
Weather vanes measure wind direction
(This old-fashioned one is on the bow of a boat.)
Modern instruments are very different from the old ones.
This vehicle is equipped with wind speed and direction sensors, and
humidity and temperature sensors.
