Dallas Semiconductor DS1921G-F5 Temperature Logger Ibutton

This Thermocron iButton is a versatile, self-sufficient system that is used for the measurement and recording of temperature. Data transfer is effected via a 1-Wire protocol.

The rate of measurement can be user-defined, and results stored as a discrete temperature or as a histogram. Up to 2048 readings can be taken at equidistant intervals ranging from 1 to 255 mins. The device can additionally record such parameters as out of range time, duration and threshold.

Suitable applications for this device include: monitoring condition of shipped goods in containers, pallets and bags, and the device will store data such as shipping information and date of manufacture.
