SWH project part 10 - temperature logging 2

Like I said yesterday, in the quiet patches between the bulk of the project making any headway, some progress has been made on my temperature monitoring system.  It all works happily enough on the desk; the next step is to get all the sensors mounted and wired up in a waterproof way and see if it still behaves out in the wet muddy real world.

Green and happy.
(no sensors plugged in just now, so values are nonsense.)

Nice and ordered in theory...

...a little more disorderly in real life.

Turning a 2D layout into a 3D structure and mounting it all in a tapering
cylindrical tub is an interesting challenge.

The multiplexer board will be mounted out at the panel site (in another
plastic tub), gathering together the inputs from 16 temperature sensors.
This means I only need 2 bits of wire 40m long instead of 16.

When panel overheat, SolarBot angry is!
He may even have a tantrum of irritating beeping noises until someone
does something about it.
