@Marshall It's always great to hear from people that their problems are solved. And it's also great that you were able to solve it on your own! I actually think that most things you'd wanna create are available through the build page. Since it's a pity to have one Arduino per sensors, the next step would be to try to combine some sketches. I mean Arduino's are relatively cheap. But if you use only 50% of their capabilities and would use another for another sensors, it will end up being more expensive than needed.
