DS1921G EVALUATION KIT AVAILABLE Thermochron iButton Device General Description The Thermochron® iButton® device (DS1921G) 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 intervals ranging from 1 to 255min can be stored. The histogram provides 63 .
