DS1925-i-button device

Analog Devices DS1925 Thermochron iButton® Temperature Logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 122K 8-bit readings or 61K 16-bit readings taken at equidistant intervals ranging from 5min to 273hrs can be stored. In addition, there are 512 bytes of nonvolatile memory for storing application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The Analog Devices DS1925 Thermochron iButton Temperature Logger is configured to and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return.
