Python UART Driver for Sensirion SVM4X\n\nThis repository contains the Python driver to communicate with a Sensirion SVM4X sensor over UART using the SHDLC protocol.\n\n\u003cimg src=\"https://raw.githubusercontent.com/Sensirion/python-uart-svm4x/master/images/svm4x.png\"\n    width=\"300px\" alt=\"SVM4X picture\"\u003e\n\nClick [here](https://www.sensirion.com/my-sgp-ek/) to learn more about the Sensirion SVM4X sensor.\n\n\nThe SVM4x evaluation kit covers evaluation of the SGP40 and SGP41 sensors.\n\n\n\n\n\n## Connect the sensor\n\nYou can connect your sensor over the provided USB cable.  \nFor special setups check out the sensor pinout in the section below.\n\n\u003cdetails\u003e\u003csummary\u003eSensor pinout\u003c/summary\u003e\n\u003cp\u003e\n\u003cimg

description and a \n[quickstart](https://sensirion.github.io/python-uart-svm4x/execute-measurements.html) example.\n\n\n## Contributing\n\nWe develop and test this driver using our company internal tools (version\ncontrol, continuous integration, code review etc.) and automatically\nsynchronize the `master` branch with GitHub. But this doesn't mean that we\ndon't respond to issues or don't accept pull requests on GitHub. In fact,\nyou're very welcome to open issues or create pull requests :-)\n\n### Check coding style\n\nThe coding style can be checked with [`flake8`](http://flake8.pycqa.org/):\n\n```bash\npip install -e .[test]  # Install requirements\nflake8                  # Run style check\n```\n\nIn addition, we check the formatting of files with\n[`editorconfig-checker`](https://editorconfig-checker.github.io/):\n\n```bash\npip install editorconfig-checker==2.0.3   # Install requirements\neditorconfig-checker                      # Run check\n```\n\n## License\n\nSee [LICENSE](LICENSE).\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsensirion%2Fpython-uart-svm4x","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsensirion%2Fpython-uart-svm4x","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsensirion%2Fpython-uart-svm4x/lists"}
