Systems of sensors and actuators can be built by wiring together many 1-Wire components. In such systems, RJ11 (6P2C or 6P4C modular plugs, commonly used for telephones) are popular. Some laboratory systems connect to 1-Wire devices using cables with modular connectors or CAT-5 cable. It could be attached to a device being monitored. It also might be a single component within a device such as a temperature probe. It might be one of many components on a circuit board within a product. Manufacturers also produce devices more complex than a single component that use the 1-Wire bus to communicate.ġ-Wire devices can fit in different places in a system. To accomplish this, 1-Wire devices include an 800 pF capacitor to store charge and power the device during periods when the data line is active.ġ-Wire devices are available in different packages: integrated circuits, a TO-92-style package (as typically used for transistors), and a portable form called an iButton or Dallas key which is a small stainless-steel package that resembles a watch battery. One distinctive feature of the bus is the possibility of using only two wires - data and ground.
The protocol is also used in small electronic keys known as a Dallas key or iButton.
A network of 1-Wire devices with an associated master device is called a MicroLAN. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. 1-Wire is a device communications bus system designed by Dallas Semiconductor that provides low-speed (16.3 kbit/s ) data, signaling, and power over a single conductor.ġ-Wire is similar in concept to I☬, but with lower data rates and longer range.
