OWFS is the 1-wire filesystem (for Linux).
1-wire is a system of cheap chips and stainless-encased (iButton) devices with a very simple communication protocol. It is featured at the Dallas/Maxim website.
The types of devices include temperature, voltage, humidity, current and contact sensors, switches and variable resistance elements, LCD controllers, memory, encryption, timers, etc. Every device has a unique 64bit address and so can be separately addressed.
The whole system looks like a virtual filesystem under OWFS. You can read the temperature just by reading a file. Great for monitoring and automation.
owfs.uci loads under /opt and uses minimal resources. Both USB and serial adapters are supported. There is a small webserver included as an alternative way to scan the sensors.
