Qwiic Pressure Sensor (BMP581) Hookup Guide
The SparkFun Pressure Sensor - BMP581 (Qwiic) and Micro Pressure Sensor - BMP581 (Qwiic) feature the BMP581 absolute pressure sensor from Bosch Sensortec. The BMP581 boasts exceptional resolution and accuracy and uses on-chip linearization and temperature compensation to provide true absolute data for pressure and temperature.
This guide will take you through the hardware present on these Qwiic breakouts, connecting them to a Qwiic circuit and using the BMP581 with the SparkFun BMP581 Arduino Library.
To follow along with this guide you will need a microcontroller to communicate with the BMP581. Below are a few options that come Qwiic-enabled out of the box:
If your chosen microcontroller is not already Qwiic-enabled, you can add that functionality with one or more of the following items:
You will also need at least one Qwiic cable to connect your sensor to your microcontroller.
If you aren't familiar with the Qwiic system, we recommend reading here for an overview.
We would also recommend taking a look at the following tutorials if you aren't familiar with them. If you are using one of the Qwiic Shields listed above, you may want to read through their respective Hookup Guides as well before going through this guide for this BMP581 Qwiic breakout.
