I'm looking to set up 6 temperature sensors, spread across a warehouse at varying heights and with very limited access to power connectors.
Cable run distance would be up to 90 meters, possibly further in future; so I guess that something like RS-422 converters and twisted pair cat 5e should allow a signal across such a distance. But was unsure about how your devices would receive power.
I was hopeful that you might be able to suggest a combination of your temp sensor + data logger + converter or whetever you think would be appropriate.
There's mention on the site that the sensors can work up to 400meters + up to 1K with the correct equipment, but I haven't yet found a technical page on the appropriate setup.
