1-Wire is a trademark of Maxim Integrated Products. While the communication speed is slow, this low-cost device is used as a bus specification that connects with only two wires.
For example, 1-Wire is used in situations where data is transmitted via quick contact, such as with warning devices and hotel door keys.
Further details are beyond the scope of this FAQ but there is large amount of information data on 1-Wire available on the Internet and in other places.
