An iButton® is a small, durably packaged module with a globally unique digital address. Enhanced by the 1-Wire® communications protocol, iButton data loggers can record and deliver data where other products cannot, such as in very harsh environments. An iButton is ideal for any application where data needs to be collected, such as temperature and humidity data logging, access control, asset management, and e-Cash transactions.
