This monograph shows you how to build a very basic but highly accurate barometric altimeter. It covers the theory behind how it works and what its limitations are. It shows how to interface a pressure sensor with a microcontroller and the calculations required to determine altitude. Software for the MSP430FR4133 microcontroller by Texas Instruments is described in detail.
