The iButton® temperature logger (DS1925) 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 DS1925 is configured and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1925 is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1925 to be mounted on almost any object, including containers, pallets, and bags.
