        CircuitPython support for the DHT11 and DHT22 temperature and humidity devices.
        
        Dependencies
        =============
        This driver depends on:
        
        * `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
        
        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>`_.
        
        Usage Example
        ==============
        
        Hardware Set-up
        ----------------
        
        The DHT11 and DHT22 devices both need a pull-resistor on the data signal wire.  
        This resistor is in the range of 1k to 5k.  Please check your device datasheet for the 
        appropriate value.
        
        Basics
        -------
        
        Of course, you must import the library to use it:
        
        .. code:: python
        
            import adafruit_dht
        
        The DHT type devices use single data wire, so import the board pin
        
        .. code:: python
        
            from board import <pin>
        
        Now, to initialize the DHT11 device:
        
        .. code:: python
        
            dht_device = adafruit_dht.DHT11(<pin>)
        
        OR initialize the DHT22 device:
        
        .. code:: python
        
            dht_device = adafruit_dht.DHT22(<pin>)
        
        Read temperature and humidity
        ------------------------------
        
        Now get the temperature and humidity values
        
        .. code:: python
        
            temperature = dht_device.temperature
            humidity = dht_device.humidity
        
        These properties may raise an exception if a problem occurs.  You should use try/raise 
        logic and catch RuntimeError and then retry getting the values after 1/2 second.

        ============
        
        Contributions are welcome! Please read our `Code of Conduct

        before contributing to help this project stay welcoming.
        
        Building locally
        ================
        
        To build this library locally you'll need to install the
        `circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.
        
        .. code-block:: shell
        
            python3 -m venv .env
            source .env/bin/activate
            pip install circuitpython-build-tools
        
        Once installed, make sure you are in the virtual environment:
        
        .. code-block:: shell
        
            source .env/bin/activate
        
        Then run the build:
        
        .. code-block:: shell
        
            circuitpython-build-bundles --filename_prefix adafruit-circuitpython-veml6070 --library_location .
        
        Sphinx documentation
        -----------------------
        
        Sphinx is used to build the documentation based on rST files and comments in the code. First,
        install dependencies (feel free to reuse the virtual environment from above):
        
        .. code-block:: shell
        
            python3 -m venv .env
            source .env/bin/activate
            pip install Sphinx sphinx-rtd-theme
        
        Now, once you have the virtual environment activated:
        
        .. code-block:: shell
        
            cd docs
            sphinx-build -E -W -b html . _build/html
        
        This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
        view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
        locally verify it will pass.
