This is the Sensirion SFM-SF06 library for Arduino allowing you to communicate with a sensor of the SFM-SF06 family over I²C.
Click here to learn more about the Sensirion SFM-SF06 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.
Sensor name | I²C Addresses |
---|---|
SFM4300 | 0x2A, 0x2B, 0x2C, 0x2D |
SFM3119 | 0x29 |
SFM3003 | 0x28, 0x2D |
SFM3013 | 0x2F |
SFM3019 | 0x2E |
The following instructions and examples use a SFM4300.
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 SFM-SF06
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
Use the following pin description to connect your SFM-SF06 to the standard I²C bus of your Arduino board:
Pin | Cable Color | Name | Description | Comments |
---|---|---|---|---|
1 | ADDR | see data sheet section 4.1 | ||
2 | SDA | I2C: Serial data input / output | Serial data, bidirectional | |
3 | GND | Ground | ||
4 | VDD | Supply Voltage | 3.0V to 5.0V | |
5 | SCL | I2C: Serial clock input | ||
6 | IRQn | Active low. see data sheet section 3.3 |
The recommended voltage is 3.3V.

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.
