DS1922T - iButton Temperature Loggers

Download the DS1922T datasheet PDF. This datasheet also covers the DS1922L variant, as both devices belong to the same ibutton temperature loggers family and are provided as variant models within a single manufacturer datasheet.

General Description

The iButtonĀ® 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.

DS1922L/DS1922T iButton Temperature Loggers with 8KB Datalog Memory General Description The iButtonĀ® 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 functions can be password protected.
