DS1922L/DS1922T
iButton Temperature Loggers
with 8KB Data-Log Memory
General Description
The iButton ? temperature loggers (DS1922L/DS1922T)
are rugged, self-sufficient systems that measure tempera-
ture 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 application-
specific information and 64 bytes store calibration data. A
mission to collect data can be programmed to begin imme-
diately, 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 config-
ured 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 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 DS1922L/DS1922T to
be mounted on almost any object, including containers,
pallets, and bags.
Applications
