The DS1921H/Z Thermochron iButtons from Dallas Semiconductor are rugged, self-sufficient systems that measure temperature and record 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 64 data bins for a resolution of 0,5°C. If the temperature leaves a user-programmable range, the DS1921H/Z will also record when this happened, and for how long. An additional 512 bytes of read/write NV memory allow storing information pertaining to the object to which the DS1921H/Z is associated. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return. The durable stainless steel package is highly resistant to environmental hazards such as dirt, moisture, and shock.
