+
+The BMP390 is a digital sensor with pressure and temperature measurement based on proven sensing principles. The sensor is more accurate than its predecessor BMP380, covering a wider measurement range. It offers new interrupt functionality, lower power, and a FIFO functionality. The integrated 512 byte FIFO buffer supports low power applications and prevents data loss in non-real-time systems.
+
+[`Bmp390`](https://docs.rs/bmp390/latest/bmp390/struct.Bmp390.html) is a driver for the BMP390 sensor. It provides methods to read the temperature and pressure from the sensor over [I2C](https://en.wikipedia.org/wiki/I%C2%B2C). It is built on top of the [`embedded_hal_async::i2c`](https://docs.rs/embedded-hal-async/latest/embedded_hal_async/i2c/index.html) traits to be compatible with a wide range of embedded platforms.

+## Datasheet
+The [BMP390 Datasheet](https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmp390-ds002.pdf) contains detailed information about the sensor's features, electrical characteristics, and registers. This package implements the functionality described in the datasheet and references the relevant sections in the documentation.
