The DS1922E temperature logger iButton? is a rugged,
self-sufficient system that measures temperature 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 273hr, can be stored.
Additionally, 576 bytes of SRAM store application-specific
information. 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 DS1922E 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 DS1922E is factory lasered with a
guaranteed unique 64-bit registration number that
allows for absolute traceability. The durable stainlesssteel
package is highly resistant to environmental hazards
such as dirt, moisture, and shock.
