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

Sensirion Core

Quick Start

Connect the SFA3X Sensor to one of your Arduino board's UART buses. We recommend using Serial2. Check the pinout of your Arduino board to find the correct pins. The pinout of the SFA3X Sensor board can be found in the data sheet.
- VDD of the SEK-SFA3X to the 3.3V of your Arduino board (5V is also possible)
- GND of the SEK-SFA3X to the GND of your Arduino board
- RX of the SEK-SFA3X to the UART2-TX of your Arduino board
- TX of the SEK-SFA3X to the UART2-RX of your Arduino board

Open the exampleUsage sample project within the Arduino IDE

 File => Examples => Sensirion UART Sfa3x => exampleUsage

Depending on your Arduino board you may need to adapt the #define SENSOR_SERIAL_INTERFACE to choose the correct serial interface.
Click the Upload button in the Arduino IDE or
```
 Sketch => Upload
```
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.
