The ds3231 has the option to allow the I2C to piggy back of the unit. So it can be connected to another device as in my case the 20x4 lcd.
The arduino uno has the 2 pins for i2c (as stated above)
SCL > A5
SDA > A4
Any I2C device should be connected to the these pins on the UNO
Any sensors can be used just make sure the correct libary and code is corrected to allow for what ever sensor it may be
