iButton
iButton® devices are small, durably packaged modules with globally unique 64-bit digital addresses.
An iButton device uses a 16mm 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, iButton devices 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.
iButton Accessories
iButton® accessories are used to establish physical and electrical connections to the device.
Attaching an iButton to an asset to be tracked or a key fob for access control is easy. Analog Devices offers several types of mounts and holders to address the needs of applications where iButton devices are used. Additionally, readers and probes enable an electromechanical connection to a device such as a PC for reading and writing to the iButtons.
Memory & Data Loggers
Data loggers and memory devices track the temperature, or temperature and humidity, of specific
assets or locations. Most data loggers offered by Analog Devices are in the rugged iButton® form factor to protect against the harsh environments they are subjected to.
