What is GSR (Galvanic Skin Response) or EDA (Electrodermal Activity\uff09<\/strong><\/h2>\n\n\n\n

GSR (Galvanic skin response) or EDA (Electrodermal Activity) refers to changes in human sweat gland activity, which can reflect the intensity of human emotional changes as known as emotional arousal<\/p>\n\n\n\n

<\/div>\n\n\n\n

How GSR or EDA works<\/strong><\/h2>\n\n\n\n

The principle is that when the human body is stimulated by the outside world or the emotional state changes, the activity of the nervous system will cause the relaxation and contraction of blood vessels in the skin and the secretion of sweat glands. At this time, the GSR sensor<\/a> is required to capture this information.<\/p>\n\n\n\n

Product Details<\/strong>:<\/strong><\/p>\n\n\n\n

Grove GSR sensor<\/a> allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand, an interesting gear to create emotion-related projects, like a sleep quality monitor. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied.<\/p>\n\n\n\n
