# Python I2C Driver for Sensirion SFM3304
This repository contains the Python driver to communicate with a Sensirion SFM3304 sensor over I2C.
Click [here](https://sensirion.com/products/catalog/SFM3304-D) to learn more about the Sensirion SFM3304 sensor.
The default I²C address of [SFM3304](https://sensirion.com/products/catalog/SFM3304-D) is **0x2E**.
## 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 | | NC | Do not connect | Ground for the heater
| 2 | red | VDD | Supply Voltage | 3.15V to 3.45V
| 3 | yellow | SCL | I2C: Serial clock input |
| 4 | black | GND | Ground |
| 5 | green | SDA | I2C: Serial data input / output |
| 6 | | NC | Do not connect | Supply voltage to the heater
