The Galvanic Skin Response (GSR), also named Electrodermal Activity (EDA) and Skin Conductance (SC), is the measure of the continuous variations in the electrical characteristics of the skin, i.e., for instance, the conductance, caused by the variation of the human body sweating.
External factors such as temperature and humidity affect EDA measurements, which can lead to inconsistent results. Internal factors such as medications and hydration can also change EDA measurements, demonstrating inconsistency with the same stimulus level. Also, the classic understanding has treated EDA as if it represented one homogeneous change in arousal across the body, but in fact, different locations of its measurement can lead to different responses.
Skin conductance (EDA or galvanic skin response, GSR) is frequently used as a psychophysiological method because it is easy to use and largely non-intrusive for the participant. EDA and GSR largely assess the activity of the “fight-or-flight response,” which is controlled by the sympathetic nervous system.
Grove GSR module allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand.
It is an interesting gear to create emotion-related projects like sleep quality monitor.
Note: This device is not a medical device.
