Great News ….. The ground temperature sensors are operating and looking good.

I am excited to see how they perform this winter and how consistent the ground temperatures are

As expected, I see the temperatures of the firs four feet fluxuating quite a bit. The sensors below four feet are fairly stable.

The only concern I have is that I may have made a mistake in construction and did not provide any earth or insulation inside the 1/2 inch CPVC piping down to the sensors. This will propbably be the next generation of sensors or a modification to be made in the spring of 2008. A little late in the season to change things now.

Stay tuned ……
