This driver enables you to use the Adafruit HTU21D-F temperature and
humidity breakout with CircuitPyton.

Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.

Installing from PyPI
====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-htu21d/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-htu21d

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-htu21d

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .env
    source .env/bin/activate
    pip3 install adafruit-circuitpython-htu21d

Usage Example
=============

.. code:: python

    import time
    import board
    import busio
    from adafruit_htu21d import HTU21D

    # Create library object using our Bus I2C port
    i2c = busio.I2C(board.SCL, board.SDA)
    sensor = HTU21D(i2c)


    while True:
        print("\nTemperature: %0.1f C" % sensor.temperature)
        print("Humidity: %0.1f %%" % sensor.relative_humidity)
        time.sleep(2)
