The DS1921G Thermochron iButton is a rugged, self-sufficient system that measures temperature and records the results in a protected memory section. The recording is done at a user-defined rate, as both a direct storage of temperature values and in the form of a histogram. Up to 2048 temperature values are taken and stored at equidistant intervals ranging from 1 to 255 minutes. The histogram 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 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 through 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.
