It doesn't look like much, but this new slab of well insulated concrete on the south side of my house on Newton Street in Denver is loaded with temperature sensors which are the first components in the computer controlled solar heating system Darren and I are designing.
The slab will act as the main "battery" gathering and storing the sun's radiant heat in this soon to be glass-enclosed porch.
The Slab poured with 9 temperature sensors embedded forever.
A sensor before being soldered to the "bus" (an ethernet cable) and cast in epoxy to protect it from the stress of being buried in a slab of concrete. Darren in the background at the helm.
Getting the old concrete out of there so we could lay a new, well insulated slab was a huge job which I never could have done without the help of Mike S.
One of nine, epoxy incased temperature sensors on the bus tied to the rebar before pouring.
The first graphic readout.
3D Map of the location of the sensors.
Note: yellow and green are two and three times as deep in concrete as the other sensors. The dark blue one is under the insulation, right up against the earth.
