HEX code is used through out the IC world.  Use of it is done mostly from what I can tell ( as I am not an engineer) at a very low level in the chips and electronic parts world.  I do not need to know any of this stuff other than I need to learn how to get it off each temp probe I am using.  To me it is nothing more than an address of the individual temp probe and tells my sketches which probe can be found where in the system.

Here is what it looks like:

0x28, 0xED, 0xED, 0xBB, 0x02, 0x00, 0x00, 0x01

If you really want to know more about this stuff here is a link to all you might want to know:

It used to be we could show off our degree of Nerdiness by yelling Hex across the lab at IBM. “That should be Zero Easy Fox Fox!”..

The 0..9 was followed by ABCDEF.. Able, Baker, Charlie, Dog, Easy, Fox…

you are right that this is just the address. Every DS18B20 made has it’s own serial number programmed into it by a laser. Some equipment has one just for the unique serial number, and doesn’t use the temperature measurement part at all…
