Barometric pressure sensor BMP581

The BMP581 is the new benchmark in the field of barometric pressure sensors and is ideally suited for a wide range of altitude tracking applications like GPS modules, wearables, hearables, smart home and industrial products. This sensor is available via our distribution partners.

More about BMP581

Building on the excellent performance and low power consumption of previous generations of Bosch sensors, our new BMP581 now delivers an entirely new level of accuracy.
Dr. Stefan Finkbeiner, CEO at Bosch Sensortec
