General Description

The iButton® temperature logger (DS1925) 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 122K

8-bit readings or 61K 16-bit readings taken at equidistant

intervals ranging from 5min to 273hrs can be stored. In

addition, there are 512 bytes of nonvolatile memory for

storing application-specific information. A mission to col-

lect 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 DS1925 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 DS1925 is factory-lasered with a

guaranteed unique 64-bit registration number that allows

for absolute traceability. The durable stainless-steel pack-

age is highly resistant to environmental hazards such as

dirt, moisture, and shock. Accessories permit the DS1925

to be mounted on almost any object, including containers,

pallets, and bags.
