1. Introduction
The BMP180 barometric pressure sensor is a device or apparatus that can sense gas pressure and convert it into usable output signals according to a certain regularity. Its basic function is to accurately measure the pressure value of the gas and convert the pressure signal into electrical signals and other signal forms that are convenient for processing and transmission, providing a basis for subsequent display, control, and data processing.
