Connecting multiple Bar02 sensors via I2C bus splitter

Hello,
I’d like to connect multiple Bar02 sensors to a Raspberry Pi via an I2C bus splitter. Connecting is trivial, but how do I access the data from the sensors? They all have the same I2C address. Does anyone have a (Python? other?) programme for that? Any tips?
Thanks a lot!

Hi @agah, welcome to the forum :slight_smile:

It’s not possible to differentiate devices on a shared bus if they all share the same address. If you need to communicate with multiple sensors then you’ll need to differentiate either using control computer hardware (e.g. a separate data line/pin per connected device), or through an I2C multiplexer instead of a bus splitter.
