iButtons and the 1-Wire® Interface

The Maxim (formerly Dallas Semiconductor) 1-Wire® interface provides an economical bidirectional link requiring only a single data line. This greatly simplifies the interface electronics, connectors and wiring required to attach peripheral devices.

Antronics Ltd has incorporated a number of 1-Wire devices into recent projects; including iButtons and temperature sensors. The example shown below reads DS1991 iButtons and also displays the temperature read from a DS1820 sensor:
