The DS1923 temperature/humidity logger iButton®
is a
rugged, self-sufficient system that measures
temperature and/or humidity 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 273hrs can be stored. In addition to
this, there are 512 bytes of SRAM for storing
application-specific information and 64 bytes for
calibration data. A mission to collect data can be
programmed to begin immediately, or after a user-
defined delay or after a temperature alarm. Access to
the memory and control functions can be password-
protected. The DS1923 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 DS1923 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 DS1923
to be mounted on almost any object, including
containers, pallets and bags.
