Introduction

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.
