Installation

PyPi Installation

This repository is hosted on PyPi as the sparkfun-qwiic-soil-moisture-sensor package. On systems that support PyPi installation via pip, this library is installed using the following commands

For all users (note: the user must have sudo privileges):

sudo pip install sparkfun-qwiic-soil-moisture-sensor

For the current user:

pip install sparkfun-qwiic-soil-moisture-sensor

To install, make sure the setuptools package is installed on the system.

Direct installation at the command line:

python setup.py install

To build a package for use with pip:

python setup.py sdist

A package file is built and placed in a subdirectory called dist. This package file can be installed using pip.

cd dist
pip install sparkfun-qwiic-soil-moisture-sensor-<version>.tar.gz

Example Use

See the examples directory for more detailed use examples.
