- The Galvanic Skin Response Sensor (GSR - Sweating) allows you to measure the electrical conductance of the skin.
- It acts as an indicator of psychological or physiological arousal.
- 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 essentially a type of ohmmeter.
