Do I need the I/O expansion to use sen0219? I am very new to arguino and am not sure what the I/O expansion does but it seems like just a micro controller can use the shield since it just has gnd, 5v, and a signal out connections.

The I/O expansion board is not necessary, but if you have the board, it will be convenient for you to use other gravity sensors. If you dont have the board, you can use the male-male Dupant line inserted into the gravity interface, then connect to the controller. You can refer to the following picture:
