suggestions for air temperature measurement

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... |

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.
