<i>owfs is a method under linux to allow 1-wire devices to appear like files in a directory. You can then enter a command like "cat */temperature" to have all the temperatures sensors measure and print their data. For instance, the collection of temperature sensors above are all on one bus, individually addressable, and will reconfigure on the fly as items are added or removed. Each device is it's own directory with it's own properties.</i> | <i>owfs is a method under linux to allow 1-wire devices to appear like files in a directory.
