Breadboards are great for prototyping but I don't like to use them for a finished project. Perf board has its uses but it still involves a fair bit of soldering and planning. To make things easier I like to use a little breakout board that I designed. It provides a ground and voltage rail and by using leads with JR plugs it very easy to connect sensors.
Below you can download the Fritzing file below in case you want to have your own boards made.
