Digital barometers, much like analog barometers, are used to forecast the weather using humidity, air pressure, and dew point. This answer needed a few more characters.
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.

There are two types of barometers, Mercury barometers and then Aenroid barometers.
it measure the atmosphere.
The pressure of air.
Mercury barometers and aneroid barometers are the most commonly used types today. Mercury barometers use a column of mercury to measure atmospheric pressure, while aneroid barometers use a small, flexible metal box to detect changes in pressure.

Barometers are used to measure pressure.
Instruments used for measuring atmospheric pressure include barometers, aneroid barometers, and electronic pressure sensors. Barometers measure pressure using a column of liquid (mercury or water) while aneroid barometers use a flexible metal capsule. Electronic pressure sensors use electronic components to capture pressure data.
mercury barometers and aneroid barometers both measure air pressure.
