Hi,

I bought this temperature sensor. https://www.sparkfun.../products/11050

I can connect it directly to the U3? I would like to use java to program it. Java libraries that I downloaded on this site can work?
I also found these libraries, http://www.maximinte...e/1wire_api.cfm but I don't know if they can help me.

Thanks

You can connect that sensor directly to the LabJack. Check out our 1-wire app note: http://labjack.com/s...pp-notes/1-wire

If you are not experienced with Java and 1-wire communication, I suggest you consider an easier temperature sensor. An analog output silicon-type sensor would be the easiest.

See the following app note:

I doubt that the Java libraries you found will be useful. More likely, you want to look at 2 things:

- Our Java wrapper for the UD driver.
- The 1-wire app note.

The important thing is that with the java library, I can read the temperature of the sensor. It will be very difficult to create the java class that is able to read the sensor, but thank you for the help.
