Grove - GSR Sensor

Grove - GSR Sensor stands for galvanic skin response, and it is a method of measuring the electrical conductance of the skin. It can be used to reflect human emotional activity. 

When we are emotionally stressed or have strong expressions on the face, sympathetic activity increases and promotes the secretion of sweat glands, which increases the skin's electrical conductivity. Grove - GSR sensor or EDA sensor allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. It is an interesting gear to create emotion-related projects like sleep quality monitors. In some galvanic skin response devices, such as lie detectors, this scientific principle is also applied.
