Detailed Description

Read pressure and sensor temperature from a BMP388 or BMP390 over I2C.

Adafruit's BMP3XX driver detects and supports both sensor variants. The underlying driver reports pressure in hectopascals; this implementation converts it to pascals before exposing it through the hardware interface.

Constructor & Destructor Documentation

__init__()

None hardware_io.environmental.bmp3xx.Bmp3xx.__init__	(		self,
		int	address = DEFAULT_ADDRESS,
		Any | None	i2c = None
	)

Create a BMP3XX sensor.

Args: address: I2C address of the sensor. i2c: Optional pre-created CircuitPython-compatible I2C bus. When omitted, the Raspberry Pi's default I2C bus is used.
