seeed studio Grove GSR Sensor Module 3.3V/5V Open Source, Galvanic Skin Response Sensor for DIY Sleep Quality Monitor Compatible with Board Arduino/Seeeduino/Raspberry Pi/BeagleBone/LinkIt ONE

Specification'Operational voltage: 3. 3V/5V. This module allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. , Galvanic Skin Response'A method of measuring the electrical conductance of the skin. It can be used to reflect the human emotional activity. When people 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. , Measure Emotions'It is an interesting gear to create emotion-related projects like sleep quality monitor. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied. , Various Main Boards Support'Grove connector compatible, it can easily connect to Arduino, Seeeduino, Raspberry Pi, BeagleBone and LinkIt ONE. , Tech Support'Visit >>Seeed Wiki<< from Seeed Studio official page for more tech support and tutorials.
