Wearable datasets with PPG and EDA

Electrodermal activity (EDA) tracks sympathetic arousal through changes in skin conductance. Combined with heart rate and heart rate variability from PPG, it is the usual input for wearable stress, emotion and workload models. These datasets record PPG and EDA together, sorted by number of subjects. Check the labelling protocol and whether the EDA signal is raw or already processed before comparing results across datasets.
