Thermochron 1921G iButton Temperature Miniature Data logger DS1921G

The DS1921G Economic Data LoggerThermochron 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 intervals ranging from 1 to 255 minutes can be stored. The histogram provides 63 data bins with a resolution of 2.0°C. If the temperature leaves a user-programmable range, the DS1921G will also record when this happened, for how long the temperature stayed outside the permitted range, and if the temperature was too high or too low. An additional 512 bytes of read/write NV memory allow storing information pertaining to the object to which the DS1921G is associated. 

Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return. Every DS1921G is factory-lasered with a guaranteed unique electrically readable 64-bit registration number that allows for absolute traceability. 

The durable stainless steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1921G to be mounted on almost any object, including containers, pallets, and bags.
