Overview EDA/GSR (Electrodermal Activity) Plux Electrodermal Activity (EDA) Sensor

Plux Electrodermal Activity (EDA) Sensor

The biosignalsplux EDA sensor is capable of accurately measuring the electrical properties of the skin which changes. These changes are caused by alterations in sweat secretion and sweat gland activity as a result of changing sympathetic nervous system activity. The low-noise signal conditioning and amplification circuit design provide optimal performance in the detection of even the most feeble electrodermal skin response events.
