A web page with meters and charts of earth temperature’s is now available at www.duanesworld.net
On this page you will find meters showing the real time temperature of the earth at depths from one foot to eleven feet. Sensors were placed at one foot intervals.
As well as the temperature meters you will also find links to charts showing the earth temperatures for the previous one hour, twenty-four hours, seven days, and thirty-one days. Soon to be added are charts showing the previous one years data.
The data is broken into three different charts. The first one shows depth one to three feet. This was done since in this location these depth temperatures fluxuate the most. The next two charts show temperatures at depths of four through seven feet and eight through eleven feet.
You can see the sensor construction, plans, and problems on the Notebook Blog at www.duanesworld.net.
