Adafruit BMP390 is a very accurate barometric pressure sensor and altimeter. It is an upgrade over previous models, such as the BMP280 and BMP388, and offers better accuracy and lower altitude noise. Here are some key features:

• High accuracy: The BMP390's relative accuracy is ±3 Pascalia, which corresponds to about ±0,25 metrin korkeutta.
• Versatile interface: It supports both I2C and SPI configurations, making it flexible for different projects.
• Temperature measurement: It can measure temperature with an accuracy of ±0,5 °C.
• STEMMA QT compatibility: The sensor is designed for STEMMA QT connectors, enabling easy, solderless connection.
