The measured gas mixture depends on the STC3x product and configured binary gas. Please refer to the datasheet and API documentation to get a list of supported binary gases.

Supported sensor types

Sensor name	I²C Addresses
STC31-C	0x29
STC31	0x29

The following instructions and examples use a STC31-C.

Connect the sensor

You can connect your sensor over a SEK-SensorBridge. For special setups, you find the sensor pinout in the section below.

Sensor pinout

Pin	Cable Color	Name	Description	Comments
1	red	VDD	Supply Voltage	2.7V to 5.5V
2	yellow	SCL	I2C: Serial clock input
3	black	GND	Ground
4	green	SDA	I2C: Serial data input / output

Contributing

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
