Building a digital barometer with Arduino to study forces due to atmospheric pressure and weather maps at schools

We describe a simple STEM project for students to learn to measure atmospheric pressure by using a sensor of the type BMP180 together with the Arduino electronic platform. The collected experimental data, together with simple experiments, can be used to study the different pressure units and the relationship between pressure and force. Also, they can be used to study basic meteorology concepts associated with the movement of air on isobar maps, and to include transversal competences related to environmental education.
