Overview
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 functions can be password protected.
The DS1922L/DS1922T are configured and communicate with a host-computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return.
Each DS1922L/DS1922T is factory lasered with a guaranteed unique 64-bit registration number...
