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.
They are more portable and can be used for airplane equipment
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.

The two main types of barometers are mercury barometers and aneroid barometers. Mercury barometers use a column of mercury in a glass tube to measure atmospheric pressure, while aneroid barometers use a sealed metal chamber that expands and contracts with pressure changes. Both types are used to predict weather changes, with mercury barometers being more precise and aneroid barometers being more portable and durable.
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.
Barometers are used to measure pressure.
mercury barometers and aneroid barometers both measure air pressure.
No! Barometers are not related to maths. They are devices used to measure atmospheric pressure... You may not be able to use barometers for maths project. - Abid
