Python Driver for Sensirion I²C Temperature and Humidity Sensors

This repository contains the Python driver to communicate with Sensirion temperature and humidity sensors using the I²C interface. For details, please read the package description in README.rst.

Note that we recommend to use the new product specific drivers for SHT3x and SHT4x.

Usage

See package description in README.rst and user manual at https://sensirion.github.io/python-i2c-sht/.

Development

We develop and test this driver using our company internal tools (version control, continuous integration, code review etc.) and automatically synchronize the master branch with GitHub. But this doesn't mean that we don't respond to issues or don't accept pull requests on GitHub. In fact, you're very welcome to open issues or create pull requests :)

Check coding style

The coding style can be checked with flake8:

pip install -e .[test]  # Install requirements
flake8                  # Run style check

In addition, we check the formatting of files with editorconfig-checker:

pip install editorconfig-checker==2.0.3   # Install requirements
editorconfig-checker                      # Run check

Run tests

Unit tests can be run with pytest:

pip install -e .[test]                             # Install requirements
pytest -m "not needs_device"                       # Run tests without hardware
pytest                                             # Run all tests
pytest -m "not (needs_device and not needs_sht3x)" # Run all tests for sht3x

The tests with the marker needs_sht3x have following requirements:

• An SHT3x device must be connected to a SensorBridge on port 1.
  • WARNING: Some tests modify non-volatile configurations of the device, restore factory defaults etc.! Do not run the tests on a device which you don't want to get modified!
• Pass the serial port where the SensorBridge is connected with --serial-port, e.g. pytest --serial-port=COM7
• The SensorBridge must have default settings (baudrate 460800, address 0)

Build documentation

The documentation can be built with Sphinx:

python setup.py install                        # Install package
pip install -r docs/requirements.txt           # Install requirements
sphinx-versioning build docs docs/_build/html  # Build documentation
