I'm looking for a setup that would allow me to continuously measure air
temperature in a confined and inaccessible area by placing several
(presumbably cabled) temperature sensors in that area before it is
closed up. The surrounding material will be rock and probably
unsuitable for wireless sensors (in addition to not being able to
replace batteries). I would like to either log the data on some sort of
console about 60 feet away, and/or feed the data into a computer. I've
check out some of the online weather stations (e.g. Davis) and they
don't do this (little cabled capability; no multiple, cabled sensors)

Can anyone suggest a (preferably online) source for a setup that will
do this? I'd prefer not to build something from scratch unless it's a
kit.


Look at Omega Instruments for thermocouples...

I love to cook with wine. Sometimes I even put it in the food.

www.phanderson.com for sensors and other hardware
www.selmaware.com/ for logging software.

Most home automation software is not well suited for logging analog
(continuously variable) data. I'd be interested in learning about event-driven
HA software that also manages analog data validation, manipulation, statistical
analysis, storage, retrieval and graphical presentation _well_ (before I
reinvent the wheel yet again ..)

You might check out HomeSeer and the mcs Temperature plug-in - it does most
of what you want; dunno if it meets your criteria of doing it _well_.

I'm about to put a 1-wire temperature sensor in each room of my house, then
use mcs Temperature to gather data aimed at characterizing and optimizing my
heating system (I've also purchased five communicating thermostats that will
be controlled by HomeSeer).

If you have an AC power recepticle in the area you can use a
Smarthome TempLinc.

Sounds to me that 1-wire might be the way to go. A two wire buss could
support the sensors, and a $20 adapter for the computer. (use a full cat 5
for distance, and to provide for expandability.)


Dallas provides some good sample code on their website for interfacing
Doing a "parasite" read on a sensor can be done on a single sensor in about
a second, Each sensor has a unique ID, and the bast part is, I've gotten
them for $3 each in to-92 cases. So, if you got 15 sensors, you can read
them about 4 times a minute if you want. They're good to +/- 1 degree c or
+/- 2 degree C based on the specific sensor

You can build sw on windows and Linux for sure (those are the only two I've
done)

I'm currently monitoring temps in my HVAC system, outside temps, and even
have one mounted in a "can cooler" near my computer that will alert me if my
beverage gets too warm.
