# Python I2C Driver for Sensirion SCD4X
This repository contains the Python driver to communicate with a Sensirion sensor of the SCD4X family over I2C.
Click [here](https://sensirion.com/products/catalog/SEK-SCD41) to learn more about the Sensirion SCD4X 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 |
| ------------- | -------------- |
|[SCD40](https://sensirion.com/products/catalog/SCD40)| **0x62**|
|[SCD41](https://sensirion.com/products/catalog/SCD41)| **0x62**|
The following instructions and examples use a *SCD41*.
## Connect the sensor
You can connect your sensor over a [SEK-SensorBridge](https://developer.sensirion.com/product-support/sek-sensorbridge/).
For special setups you find the sensor pinout in the section below.
Sensor pinout
| *Pin* | *Cable Color* | *Name* | *Description* | *Comments* |
|-------|---------------|:------:|----------------|------------|
| 1 | yellow | SCL | I2C: Serial clock input |
| 2 | black | GND | Ground |
| 3 | red | VDD | Supply Voltage | 2.4V to 5.5V
| 4 | green | SDA | I2C: Serial data input / output |
