Pressure sensors measure the absolute pressure of the fluid around them. This includes air, water, and anything else that acts like a viscous fluid. Depending on how you interpret the data, you can determine altitude, water depth, or any other tasks that require an accurate pressure reading.

Covered in This Tutorial

We will show you how to connect this sensor to an Arduino microcontroller and use the included software library to get measurements out of the sensor. We'll also show you how to interpret the readings showing changes in altitude and water depth.
