CaseyTheRobot Introduction
The T5403 is a barometric pressure sensor with an I2C ("Wire") interface. Barometric pressure sensors measure the absolute pressure of the air around them. This pressure varies with both the weather and altitude. Depending on how you interpret the data, you can monitor changes in the weather, measure altitude, 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 for both monitoring the weather and showing changes in altitude.
