The MCP9808 is an awesome, high accuracy temperature sensor that communicates

over I2C. Its available on `Adafruit as a breakout `_.

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 locally `from

PyPI `_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-mcp9808

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-mcp9808

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-mcp9808

Usage Notes

===========

Getting the temperature in Celsius is easy! First, import all of the pins from

the board, board.I2C() for native I2C communication and the thermometer library

itself.

.. code-block:: python3

  import board

  import adafruit_mcp9808

Next, initialize the I2C bus in a with statement so it always gets shut down ok.

Then, construct the thermometer class:

.. code-block:: python3

  # Do one reading

  with board.I2C() as i2c:

      t = adafruit_mcp9808.MCP9808(i2c)

      # Finally, read the temperature property and print it out

      print(t.temperature)
