Want to add altitude tracking or weather monitoring to your Arduino project? The BMP180 barometric pressure sensor makes it effortless! This compact and powerful sensor measures temperature and atmospheric pressure, which can be used to determine altitude and track weather patterns.
In this tutorial, I’m going to show you how to setup the BMP180 on an Arduino, so you can measure barometric pressure, and altitude from the ground or from sea level.
BMP180 is a high precision sensor designed for consumer applications. Barometric Pressure is nothing but weight of air applied on everything. The air has weight and wherever there is air its pressure is felt. BMP180 sensor senses that pressure and provides that information in digital output.
In this tutorial, we will learn how to work the BMP 180 pressure sensor with Arduino code. This sensor has a very small shape through which the atmospheric pressure can be measured. Also, as this pressure decreases as it rises above sea level, it can also be used to get altitude and monitor weather changes.
