GSR Galvanic Skin Response Module Current Sensor Kit V2.0

The GSR (Galvanic Skin Response) Module is an essential tool for measuring electrodermal activity (EDA) or skin conductance response (SCR). This sensor captures the physiological phenomenon where the skin becomes a better conductor of electricity during moments of emotional or physical arousal. By monitoring these subtle changes, this module acts as a window into the human autonomic nervous system.

Advanced Physiological Sensing

This updated version of the GSR sensor offers significant improvements over previous generations, featuring higher precision and a more stable performance profile. It operates essentially as a highly sensitive ohmmeter, measuring the electrical conductance between two points on the skin. When a user experiences arousal, sweat gland activity increases, raising skin conductance and allowing the module to detect the change instantly.

Reliable and Versatile Performance

Designed for seamless integration with microcontrollers, this kit is ideal for creating biofeedback systems and lie detector-style experiments. With a tiny footprint and a low current draw of just 1mA, it is perfect for portable research tools and long-term educational projects.
