Sensirion I²C SF06-LF Arduino Library

This is the Sensirion SF06-LF library for Arduino allowing you to communicate with a sensor of the SF06-LF family over I²C.

Click here to learn more about the Sensirion SF06-LF sensor family.

Not all sensors of this driver family support all measurements. In case a measurement is not supported by all sensors, the products that support it are listed in the API description.

Supported sensor types

For instructions how to change the I2C address of your SLF3x sensor please refer to examples/exampleI2cAddressChange/README.md.

The following instructions and examples use a SLF3C-1300F.

Installation of the library

This library can be installed using the Arduino Library manager: Start the Arduino IDE and open the Library Manager via

Sketch ➔ Include Library ➔ Manage Libraries...

Search for the Sensirion I2C SF06-LF library in the Filter your search... field and install it by clicking the install button.

If you cannot find it in the library manager, 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 library manager or Add .ZIP Library

Dependencies

• Sensirion Core

Sensor wiring

Use the following pin description to connect your SF06-LF to the standard I²C bus of your Arduino board:

The recommended voltage is 3.3V.

Board specific wiring

You will find pinout schematics for recommended board models below:

Quick Start

1. Install the libraries and dependencies according to Installation of the library

2. Connect the SF06-LF sensor to your Arduino as explained in Sensor wiring

3. Open the exampleUsage sample project within the Arduino IDE:

   File ➔ Examples ➔ Sensirion I2C SF06-LF ➔ exampleUsage

   The provided example is working with a SLF3C-1300F, I²C address 0x08. In order to use the code with another product or I²C address you need to change it in the code of exampleUsage. You find the list with pre-defined addresses in src/SensirionI2CSf06Lf.h.

4. Click the Upload button in the Arduino IDE or Sketch ➔ Upload

5. 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 used tool 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.
