This repository contains the Python driver to communicate with a Sensirion sensor of the SCD4X family over I2C.
Click here 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 | 0x62 |
| SCD41 | 0x62 |
| SCD43 | 0x62 |
The following instructions and examples use a SCD41.
Connect the sensor
You can connect your sensor over a SEK-SensorBridge. For special setups you find the sensor pinout in the section below.
