Finally got Photon publishing the data after the 2nd-to-last sensor arrived today. Happy about that.
I got the finally sensor today also, but I am very unfamiliar with it, it might take me some time to get it published too. In any case, it is an air particle counter.
In any case, besides bragging about this (I know, I know there are TONS of them out there), I wanted to thanks those that helped with code samples and questions with problems that I encountered.
