Python library for TE HTU31D temperature and humidity sensors


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://circuitpython.org/libraries>`_.

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-htu31d/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-htu31d

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-htu31d

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-htu31d

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

.. code-block:: python

    import time
    import board
    import adafruit_htu31d

    i2c = board.I2C()  # uses board.SCL and board.SDA
    htu = adafruit_htu31d.HTU31D(i2c)
    print("Found HTU31D with serial number", hex(htu.serial_number))

    htu.heater = True
    print("Heater is on?", htu.heater)
    htu.heater = False
    print("Heater is on?", htu.heater)

    while True:
        temperature, relative_humidity = htu.measurements
        print("Temperature: %0.1f C" % temperature)
        print("Humidity: %0.1f %%" % relative_humidity)
        print("")
        time.sleep(1)
