CircuitPython driver from BMP280 Temperature and Barometic Pressure sensor

Installation and Dependencies

=============================

This driver depends on:

* `Adafruit CircuitPython `_

* `Bus Device `_

Please ensure all dependencies are available on the CircuitPython filesystem.

This is easily achieved by downloading

`the Adafruit library and driver bundle `_.

Installing from PyPI

--------------------

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver

`from PyPI `_. To install

for the current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-bmp280

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-bmp280

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name

    python3 -m venv .venv

    source .venv/bin/activate

    pip3 install adafruit-circuitpython-bmp280

Usage Example

=============

.. code-block:: python

    import time

    import board

    # import digitalio # For use with SPI

    import adafruit_bmp280

    # Create sensor object, communicating over the board's default I2C bus

    i2c = board.I2C()   # uses board.SCL and board.SDA

    bmp280 = adafruit_bmp280.Adafruit_BMP280_I2C(i2c)

    # OR Create sensor object, communicating over the board's default SPI bus

    # spi = board.SPI()

    # bmp_cs = digitalio.DigitalInOut(board.D10)

    # bmp280 = adafruit_bmp280.Adafruit_BMP280_SPI(spi, bmp_cs)

    # change this to match the location's pressure (hPa) at sea level

    bmp280.sea_level_pressure = 1013.25

    while True:

        print("\nTemperature: %0.1f C" % bmp280.temperature)

        print("Pressure: %0.1f hPa" % bmp280.pressure)

        print("Altitude = %0.2f meters" % bmp280.altitude)

        time.sleep(2)
