Thermochron iButton

DS921G

General Description

Features

♦ Digital Thermometer Measures Temperature in

The DS1921G Thermochron 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, both as a direct storage of

temperature values as well as in the form of a histogram.

Up to 2048 temperature values taken at equidistant inter-

vals ranging from 1 to 255min can be stored. The his-

togram provides 63 data bins with a resolution of 2.0°C.

If the temperature leaves a user-programmable range,

the DS1921G also records when this happened, for how

long the temperature stayed outside the permitted range,

and if the temperature was too high or too low. An addi-

tional 512 bytes of read/write nonvolatile (NV) memory

allows storing information pertaining to the object to

which the DS1921G is associated. Data is transferred
