Sensirion I2C SGP40 Arduino Library

This is the Sensirion SGP40 library for Arduino using the modules I2C interface.

Click here to learn more about the SGP40 sensor.

Installation

To install, download the latest release as .zip file and add it to your Arduino IDE via

Sketch => Include Library => Add .ZIP Library...

Don't forget to install the dependencies listed below the same way via Add .ZIP Library

Note: Installation via the Arduino Library Manager is coming soon.

Dependencies

Quick Start

  1. Connect the SGP40 Sensor to your Arduino board's standard I2C bus. Check the pinout of your Arduino board to find the correct pins. The pinout of the SGP40 Sensor board can be found in the data sheet.

    • VDD of the SEK-SGP40 to the 3.3V of your Arduino board
    • GND of the SEK-SGP40 to the GND of your Arduino board
    • SCL of the SEK-SGP40 to the SCL of your Arduino board
    • SDA of the SEK-SGP40 to the SDA of your Arduino board

  2. Open the exampleUsage sample project within the Arduino IDE

     File => Examples => Sensirion I2C SGP40 => exampleUsage

  3. Click the Upload button in the Arduino IDE or

     Sketch => Upload

  4. When the upload process has finished, open the Serial Monitor or Serial Plotter via the Tools menu to observe the measurement values. Note that the Baud Rate in the corresponding window has to be set to 115200 baud.

Contributing

Contributions are welcome!

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 :)

This Sensirion library uses clang-format to standardize the formatting of all our .cpp and .h files. Make sure your contributions are formatted accordingly:

The -i flag will apply the format changes to the files listed.

clang-format -i src/*.cpp src/*.h

Note that differences from this formatting will result in a failed build until they are fixed.
