I'd like to build an Arduino base project that can log data from thermometers. The thermometers would be placed at various places in a hall building, sub floor, slab (with hydronic heating elements), air, roof cavity and roof exterior (ideally).
The data would be logged to an SD card or some other at regular intervals. Purpose is to study ESD characteristics of the building and monitor effect mechanical air flow directed from sub-floor rooms to hall. May later be used to control processes but that's not important at present.
The distance of the sensors would vary from a few meters to perhaps 15m max but through materials like a 250mm bond-deck reinforced concrete slab and roofing metal. I'm expecting that rules out Wireless but I would have the faintest idea what I'm talking about.
Can I reasonable expect to get data across wires for those distances?
What kind of options are available for sensor devices that would suit say a 0-70 degC range. accurate to 1 dp would be great but 0dp adequate I guess. Anybody made a project like this before?
I'm totally new to Ardunio but in the 80s made a few things including a 7 PCB monophonic synth with thousands of solder joins so I'm game to go digital. ;)
