3 Overview

The barometer is an atmospheric pressure measuring instrument that outputs (displays) the barometric pressure in digital form (including an integrated gauge The atmospheric pressure measuring unit satisfying the above-mentioned form). The structure of the barometer can be divided into a sensor and display unit for one The separation of the body and the separation of the sensor from the display unit is typically used to measure atmospheric pressure. Its working principle such as Figure 1 shows the measured pressure through the pressure medium on the pressure sensor, the pressure sensor output the corresponding electrical signal, The value is output (displayed) by the signal processing unit. Figure 1 Barometer works
