iButton - iButton Devices - One Wire
iButton® devices are small, durably packaged modules with globally unique digital addresses. An iButton device uses a stainless steel 'can' as an electronic communications interface. The iButton can has a data contact, called the 'lid', and a ground contact, called the 'base'. Each of the iButton contacts is connected to the silicon chip inside. The iButton base includes a flange to simplify attaching the iButton device to just about anything.
Enhanced by our 1-Wire communications protocol, iButtons provide the ability to deliver or record data where other products cannot, such as in very harsh environments. An iButton device is ideal for any application where information needs to follow a person or object, such as temperature and humidity data logging, access control, asset tracking, and electronic cash (eCash) transactions.
