|  Re: Plus42Wire - I2C Bus Interface
Yes, the I2C protocol is used a lot for connecting sensors. You can see this very frequently in the Arduino world. It has the pro of using only two wires, but it is relatively slow, since the address must be transmitted first for every communication and since it is sort of half-duplex.
SPI is a similar protocol that is faster and full-duplex but it requires one more wire per peripheral. Be patient for that...
