I managed to clean up the images above, the way I was hosting them before I could see everything but no one else could. Hopefully that clears up some confusion.

I ran two temp tests overnight. First I placed all my temp probes in a sealed thermos in a closed room. You can see from the plot below that the sensors are all reading a bit off from each other. This is a plot of the difference between the first probe and the others, basically a measure of there relative error. They should be accurate to within a degree but they are fluctuating by 2 degrees instead. Considering we are seeing only 4-8 degrees of temp differential in the house that is not nearly sensitive enough.



Next I filled the bottom of the thermos up with ice, while keeping the probes dry, and let it sit for a while. Here is a plot of the difference in readings from the first probe to all the others. You can see that there is no consistent pattern to the temp offset, we can't just subtract or add a degree to bring them into allignment.



I don't think I can really move forward with these probes. So I'm looking into some i2c temp probes that have a 0.3 C accuracy and a finer resolution. Hopefully they are close enough. On top of that I'm considering building a wooden rocket box to compare the temperatures against.

In the meantime while I'm waiting on parts I will make a test print at various thicknesses, and look into alternate ways to texture the inside of the house.
