MAKE: Blog: Temperature logger kit

Temperature logger kit

If you need to log/store temperatures, this looks like a pretty interesting kit that uses iButtons - "The DS1921 included in this kit is a complete self contained temperature data logger measuring only 17.35mm wide and 5.89mm thick. It has an accuracy of +/- 1°C from -30°C to +70°C. A built in real-time clock and timer has accuracy of +/- 2 minutes per month. The logger automatically wakes up and measures temperature as user-programmable intervals from 1 to 255 minutes. Logs up to 2048 consecutive temperature measurements are recorded in protected nonvolatile random access memory. A long-term temperature histogram is also recorded with a 2.0°C resolution. There are programmable temperature-high and temperature-low alarm trip points available. The device records 24 time stamps and durations when temperature leaves the range specified by the trip points. 512 bytes of general purpose read/write nonvolatile randam access memory is available for user programming of various information such as placement location information." - Link.
