The iButton® high-temperature logger (DS1922E) 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 8192 8-bit readings or 4096 16-bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 576 bytes of SRAM store application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm.
