ibutton-left-nondominant-upper-arm-cotton-sports-wristband-radial-artery-ventral-interior-5min-v2

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. This sensor should allow to capture circadian rhythm modulations. See the works of Dr. Antonio Martinez Nicolas for more details on wrist skin temperature rhythm and WTIO. The procedure is described in: https://pubmed.ncbi.nlm.nih.gov/18761026/ Part of the MyNon24Sleep v2 dataset, specifications of the study's design and wearables setup available in the Wearadian v2 project's documentation. Data starts from 2022-03-17 and will cover one whole year. Data is discontinuous, each csv file should be concatenated with the next ones based on datetime to get the full dataset. This dataset can be used alone or in combination with ibutton-left-nondominant-upper-arm-cotton-sports-wristband-dorsal-interior-5min-v2 to regress dorsal skin temperature. There are no recordings for ambient temperature in Wearadian v2. The maximum number of samples seems to be 62720, which is about about 6-7 months of continuous data recording maximum per run. So it's necessary to clear the sensor's data before collecting a new period. Note that the datetime in the filename is in US format: monthdayyear.
