BMP390L - pressure and temperature sensor - STEMMA QT / Qwiic - Adafruit 4816

Sensormodule equipped with BoschBMP388andBMP390digitalbarometer. Enables precise measurement of pressure and height in the pressure rangefrom 300 hPa to 1250 hPa, with relative measurement accuracy of± 0,08 hPaand absolute measurement accuracy of ±0,5 hPa. Powered by voltage in range of3 V to 5 V DC. The module uses I2C and SPI bus to communicate with the main module, e.g. Arduino orMetro. Equipped with STEMMA QT / Qwiic connectors, which can be used to connect sensor with microcontroller.
