CJMCU-6701 GSR Skin Sensor Analog SPI Module

• A precise 12bit AD converter
• Detects conductance of the skin

GSR Sensor stands for Galvanic Skin Response. 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.

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.
