I did a little work on the Mud-Py Analyser this evening, adding in a synchronized "secondary zone view" so that I can compare data from two sensor types at once.
I especially wanted to be able to view soil moisture and temperature at the same time.
The video below is a comparison of soil moisture and temperature for the last 20 days.
There's some surprises in there, at least for me.
I expected something simple like "hotter = dryer."
It ain't so.
It turns out that there's significant changes in soil moisture during the night time. There are times when it is cool at night, and the soil moisture just drops only to climb again.
This is the kind of thing I expected:
That's a warm afternoon with temperatures above 25 degrees C (heading for 80 degree F.) The soil moisture dropped drastically in the areas I would expect it to. The lower edge is the street, and the right edge is the driveway - the street and the driveway both have deep layers of crushed rock that don't hold moisture at all.
What I didn't expect was this:
I'll see about implementing dual views for the individual sensors, and see what that can tell me.
