I'm a little behind on this, but here's what the data looks like. This is a screenshot of what is on my ph when I collect the temp history. It measures to the tenth of a degree. It's sensitivity is pretty amazing (at least to me). It shows all data since the previous download of temp data.
This sensor was sitting on a window sill instead of in my pond. I'm guessing the two little spikes late morning on March 8 are very likely when our automatic blinds raised themselves.
