The barometric pressure sensor BMP180 is designed to read the atmospheric pressure and thus indirectly estimate the height above sea level. The atmospheric pressure is the force exerted by the air (atmosphere) on the surface of the earth. The atmospheric pressure is due to the weight of the air column over a certain area, that is why when measuring the atmospheric pressure in higher altitude points, the pressure value is lower because the amount of air is lower. The atmospheric pressure also varies with the climate, mainly with the temperature, since it changes the density of the air, which is reflected in a change in the weight and therefore in a change of pressure.
