GSR Skin Electrical Sensor Kit (Sweat Sensor)

Description

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.
