How can I connect more I2C sensor, in a unique port?

I need to connect more sensor with I2C protocol, but I have only one I2C port, how I can connect more sensor in the same port?

I2C is a bus so you can connect many sensors to the same "port". Just ensure that the pull-ups are set only once per bus and that each sensor has a unique address.

Thank you, how can I set the pull ups? Do you know where I can find a practical example?

how can I set the pull ups?

Use two resistors that match your bus’ capacity.

Do you know where I can find a practical example?

Do you know how to use Google? There are thousands of examples on the net.
