Python I2C Driver for Sensirion SFM-SF06
This repository contains the Python driver to communicate with a Sensirion 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.
Supported sensor types
| 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.
Connect the sensor
You can connect your sensor over a SEK-SensorBridge. For special setups you find the sensor pinout in the section below.
