Datasheet Summary
DS1922L/DS1922T iButton Temperature Loggers with 8KB Datalog Memory
General Description
The iButton® temperature loggers (DS1922L/DS1922T) are rugged, self-sufficient systems that measure temperature and record 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, 512 bytes of SRAM store applicationspecific information and 64 bytes store calibration data. 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...
