FAQs for the BMP390

The BMP390 is intended for applications such as altitude tracking, indoor navigation, GPS enhancement, drones, wearables, sports and fitness applications, AR/VR and weather monitoring.

Its precise pressure measurements can be used to detect altitude changes such as floor changes and elevator movements, supporting indoor localization.

Yes. Bosch describes the BMP390 as suitable for integration with IMUs to improve sensor-fusion performance, robustness and stability in navigation and fitness applications.

The FIFO enables sensor data to be buffered while reducing host activity, which can lower overall system power consumption and prevent data loss in non-real-time systems.

Yes. Bosch lists vertical velocity indication, such as rise or sink speed, as a typical application.
