Pressure sensor BMP390
High-performance. Accurate. Stable.
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.
