Pressure sensor BMP390
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, such as smartphones, GPS modules, wearables, hearables and drones.
- Best performance in market
- Unique accuracy and stability
- Lowest noise
