Could anybody tell me how to connect SCD41 (i2c) sensor to Domoticz on raspberry pi please ?

You cannot directly.
You will have to write a python or bash script running on your Raspberry to update a dummy virtual device.

See for example: viewtopic.php?t=33516

Thanks for answering. Unfortunately, as I am illiterate in programming, I was hoping somebody had done it. Thanks anyway.

Perhaps find a CO2 meter that can be connected to Domoticz?

you can use an esp8266 or esp32 with tasmota.
the sensor is supported in tasmota as it is listed here on line 62: https://tasmota.github.io/docs/I2CDEVIC ... 2c-devices
