The body that can be used to measure the electrical activity of the skin (EDA), also known as the galvanic skin response (GSR). EDA is actually a characteristic of the human body that leads to continuous changes in the electrical properties of the skin. EDA monitoring is usually combined with monitoring of heart rate, respiratory rate, and blood pressure to fully understand some parameters of the human autonomic nervous system.
EDA measurements are an integral part of modern lie detectors and are often used as lie detectors. GSR clicks are ideally suited as an experimental tool for research, as well as for establishing effective test applications based on EDA reactions – such as polygraphs.
MCP607 2.5V to 6.0V Micropower CMOS Op Amp, MCP3201 2.7V 12-Bit A/D Converter with SPI Serial Interface, MCP1541 2.5V, and 4.096V
The click features a precise 12bit AD converter so that the measured data can be digitally processed by the MCU via the SPI, it also outputs buffered analog signal for further processing (analog or digital)
