ibutton-left-nondominant-upper-arm-cotton-sports-wristband-5min

Skin temperature using a Maxim Thermocron iButton DS1925L set at a resolution of one sample every 5 min (max resolution) and temperature resolution of 0.0625°C (max resolution), placed on the radial artery on the forearm (between elbow and wrist, about in the middle with a slightly changing position regularly to avoid skin damage due to continuous skin obstruction and warmth), by being attached with a velcro to the interior of a cotton sports wrist band. See the works of Dr. Antonio Martinez Nicolas for more details on wrist skin temperature rhythm and WTIO.<br>The procedure is described in: https://pubmed.ncbi.nlm.nih.gov/18761026/<br>This dataset can be used alone or in combination with ibutton-left-nondominant-upper-arm-cotton-sports-wristband-dorsal-interior-5min and ibutton-left-nondominant-upper-arm-cotton-sports-wristband-ventral-exterior-5min to regress dorsal skin temperature and ambient temperature respectively.<br>Start using the files from the datetime (in filename): 071621 and onward. Indeed, earlier logs are redundant. Concatenate every files beyond this date to get the full log, each file containing one distinct period of time.<br>Earlier logs contain the same data as 071621, as initially it was thought that the sensor had enough memory to collect 1 year of data, but this was in fact incorrect (it's about 6-7 months of data). So it's necessary to clear the sensor's data before collecting a new period.<br>There is unfortunately some missing data from 2021-07-06 to 2021-07-16 because the internal memory was unexpectedly already filled (it should have been able to store more than a year according to the manufacturer's documentation). The maximum number of samples seems to be 62720.<br>Note that the datetime in the filename is in US format: monthdayyear.<br>
