Grove - GSR sensor - electrical resistance of the skin

The module is equipped with a sensor GSR, using the galvanic-skin reaction. Strong emotions cause the stimulus that is transmitted to the sympathetic nervous system causing increased secretion of sweat through the sweat glands so it changes the electrical resistance of the skin depending on its moisture. Sensors of this type are used in psychophysiology, they reflect the stress response, experienced emotions, and activity level. It is powered with the voltage of 5 V. It has an analog input that makes it compatible with most commissioning modules, including Raspberry Pi and Arduino.

The module is equipped with Grove interface that facilitates its connection to the Arduino along with Base Shield v2.0 or Raspberry with Hat from GrovePi+.
