The galvanic skin response (GSR), also known as Skin Conductance (SC), refers to changes in sweat gland activity, which reflect the intensity of participants’ emotional state – or ’emotional arousal’. … Our level of emotional arousal changes in response to the environment we’re in.
- 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 is essentially a type of ohmmeter.
- Input voltage: 5V/3.3V
- Sensor sensitivity: adjustable through a resistor on board
