# Python I2C Driver for Sensirion SFA3X
This repository contains the Python driver to communicate with a Sensirion SFA3X sensor over I2C.
Click [here](https://sensirion.com/products/catalog/SEK-SFA30) to learn more about the Sensirion SFA3X sensor.
The default I²C address of [SFA3X](https://sensirion.com/products/catalog/SFA30) is **0x5D**.
## Connect the sensor
You can connect your sensor over a [SEK-SensorBridge](https://developer.sensirion.com/sensirion-products/sek-sensorbridge/).
For special setups you find the sensor pinout in the section below.
Sensor pinout
| *Pin* | *Cable Color* | *Name* | *Description* | *Comments* |
|-------|---------------|:------:|----------------|------------|
| 1 | red | VDD | Supply Voltage | 3.15V to 5.5V
| 2 | black | GND | Ground |
| 3 | green | SDA | I2C: Serial data input / output |
| 4 | yellow | SCL | I2C: Serial clock input |
| 5 | blue | SEL | Interface select | Pull to GND to select I2C (leaving it floating selects UART)
