Yeah I'll definitely add Celsius! It's funny I'm using Kelvin and Celsius internally, but the people it's for are very Fahrenheit dependent.
As for water stratification, it's actually on the shore of 30ft deep lake! It's just so close to the surface that it doesn't really matter here. I want to try and measure stratification, but I would need a long cable to get far enough out. Do you know of any temperature sensors that would work well over 100ft of cable?

This is a project that's been running for almost 2 years now. Everything is still working with very little down time! The solar power system is way overpowered for what it's doing, but I wanted to make sure it works through the dark winters.
The temperature sensor is at the bottom of a bucket in the ground, because the water level gets pretty low in the winter and I didn't want the ice to destroy the temperature sensor when it drifts.
Any thoughts or suggestions for improvements are welcome!
