A GSR (Galvanic Skin Response) Sensor measures skin conductivity changes caused by sweat gland activity, indicating emotional arousal or stress levels. It is commonly used in psychological research, biofeedback, and wearable health monitoring applications.
GSR SENSOR
DESCRIPTION
Skin conductance, also known as galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. This is of interest because the sweat glands are controlled by the sympathetic nervous system, so moments of strong emotion, change the electrical resistance of the skin. Skin conductance is used as an indication of psychological or physiological arousal; the device measures the electrical conductance between 2 points, and is essentially a type of ohmmeter.GSR allows you to spot such strong emotions by simple attaching two electrodes to two fingers on one hand.
