iButton DESCRIPTION The DS1921G Thermochron iButton is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done ata 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.SPECIAL FEATURES Digital thermometer measures temperature in 0.5°C increments Accuracy ±1°C from -30°C to +70°C. See EC table for accuracy specification Built-in real-time clock (RTC) and timer has accuracy of ±2 minutes per month from 0°C to 45°C Water resistant or waterproof if placed inside DS9107 iButton® capsule (Exceeds Water Resistant 3 ATM requirements) Automatically wakes up and measures temperature at user-programmable intervals from 1 to 255 minutes Logs up to 2048 consecutive temperature measurements in protected nonvolatile (NV) random access memory Records a long-term temperature histogram with 2.0°C resolution Programmable temperature-high and temperature-low alarm trip points Records up to 24 time stamps and durations when temperature leaves the range specified by the trip points 512 bytes of general-purpose read/write NV random access memory Communicates to host with a single digital signal at 15.4kbits or125kbits per second using 1-Wire® protocol
