C185 and BMP180, how to connect?

Hi, I am very new to C185, and sensors too.
I have a BMP180 sensor.

As far as I know this is I2C communication, so digital sensor.
And also C185 receives digital input too.
However, from my knowledge, BMP180 has two signal lines - SCL, SDA - but C185 looks like have just one signal line for digital input. Am I right?
How should I connect this sensor to C185? Begging for your help.
Thank you!
