Pressure sensor BMP380
Small. High performance. Low noise.
BMP380
Pressure sensor
The BMP380 is a very small, low-power and low-noise 24-bit absolute barometric pressure sensor specifically designed and ideally suited for a wide range of altitude tracking applications. BMP380 offers outstanding design flexibility, providing a single package solution that can be easily integrated into a multitude of existing and upcoming devices such as smartphones, GPS modules, wearables and drones. The sensor is more accurate than its predecessors, covering a wide measurement range.
