Large 1-wire network (20+), Java interfacing

[csverhul]

I am trying to build a system to measure the temperatures at 20+ different locations (all in same server room). I need a way of getting all that data to a host pc and in a format that is usable by a Java program that I'll write in the future.

First off is this possible? Has anyone here been successful in getting multiple sensors working in a custom Java program?

I plan on using these sensors: http://www.ibuttonlink.com/t-sense.aspx and the 6 channel master hub from hobby boards.

I am new to 1-wire so any guidance would be appreciated.

Thank you!

There is a lot of Java code available for 1-Wire. You can start at the Weather Toys website.

You may also look thread http://www.cocoontech.com/forums/index.php?showtopic=11392 , I recreate Java library which look little better if you use more devices :huh: and couplers.

A while back I needed to do the same thing in a server room and adjacent UPS room. It was a relatively small server room (250-300 servers) which I expanded about 30% and had a budget of less than 500k to do said expansion.

While at home I use multiple 1-Wire sensors connected to a Temp05, two Temp08's and two 9097's I decided to buy an off the shelf product for the server room with the ability to utilize numerous types and multiple environmental sensors.

Aside from having the ability to do broadcast emails to support infrastructure I needed a simple plug n play, easily documented and repaired system.
