Adafruit BMP390 Precision Barometric Pressure & Altimeter is precise and ideal for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations. The BMP390L is the next-generation of sensors from Bosch and is the upgrade to the BMP280 and BMP388 – with a low-altitude noise as low as 0.1m and the same fast conversion time.
