BMP390

Pressure sensor

The BMP390 is a very small, low-power and low-noise 24-bit absolute barometric pressure sensor. The digital, high-performance sensor is ideally suited for a wide range of altitude tracking applications. This new BMP390 pressure sensor offers outstanding design flexibility, providing a single package solution that customers can easily integrate into a multitude of existing and upcoming devices such as smartphones, GPS modules, wearables, hearables and drones.

Smartphones & tablets

Smartphone as life saver: Pressure sensors inside smartphones help to localize people indoors, where GPS signals are not available. This enables first responders to determine the floor level of smartphone users who trigger an emergency call – potentially saving thousands of lives.

Wearables & hearables

Learn what you burn: Pressure sensors inside smartwatches or headphones increase the precision of calorie tracking by up to 15 percent! This is enabled by accurate altitude detection, that precisely determines whether a user is walking up or down a gradient or stairs.
