EVALUATION KIT AVAILABLE Thermochron iButton Device DS1921G General Description Benefits and Features The Thermochron iButton device (DS1921G) is a High Accuracy, Full-Featured Digital Temperature rugged, self-sufficient system that measures temperature Logger Simplifies Temperature Data Collection and and records the result in a protected memory section. Dissemination of Electronic Temperature Record The recording is done at a user-defined rate, both as a Accuracy 1C from -30C to +70C (See the direct storage of temperature values as well as in the Electrical Characteristics for Accuracy Specification) form of a histogram. Up to 2048 temperature values Digital Thermometer Measures Temperature in taken at equidistant intervals ranging from 1 to 255min 0.5C Increments can be stored. The histogram provides 63 data bins with Built-In Real-Time Clock (RTC) and Timer Has a resolution of 2.0C. If the temperature leaves a user- Accuracy of 2 Minutes per Month from 0C to +45C programmable range, the DS1921G also records when Automatically Wakes Up and Measures this happened, for how long the temperature stayed out- Temperature at User-Programmable Intervals from side the permitted range, and if the temperature was too 1 Minute to 255 Minutes high or too low. An additional 512 bytes of battery- Logs Consecutive Temperature Measurements in backed SRAM allow storing information pertaining to the 2kB of Datalog Memory object to which the DS1921G is associated. Data is Records a Long-Term Temperature Histogram with transferred serially through the 1-Wire protocol, which 2.0C Resolution requires only a single data lead and a ground return. Every DS1921G is factory lasered with a guaranteed Programmable Temperature High and Temperature unique, electrically readable, 64-bit registration number Low Alarm Trip Points that allows for absolute traceability.
