ANATOMY

Detailed explanation-1: -A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.

Detailed explanation-2: -It helps you understand weather patterns. Thus, higher pressure is indicative of calm weather, while low barometric pressure indicates poor weather. Meteorologists and sailors use fluctuations in barometric pressure to forecast weather conditions.

Detailed explanation-3: -Atmospheric pressure is measured by a barometer that employs a silicon capacitive pressure sensor having excellent repeatability and long term stability characteristics.

Detailed explanation-4: -Instruments used to measure and display pressure mechanically are called pressure gauges, vacuum gauges or compound gauges (vacuum & pressure). The widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge.

Detailed explanation-5: -Hence, Barometer is used to measure air or atmospheric pressure.
