Grove- skin electrical sensor

Grove- skin electrical sensor
GSR (galvanicskinresponse) in Grove-GSR Sensor means skin electrical response. When we feel nervous or have strong facial expressions, sympathetic nerve activity will increase and sweat gland secretion will increase, which will lead to an increase in skin conductivity. This sensor can measure the conductivity of your surface skin by sticking two electrodes to two fingers adjacent to each other, so as to judge whether you had strong facial expressions at that time. Some highly sensitive lie detectors use this scientific principle.
