Seeed Grove GSR Skin Response Sensor

The Seeed Studio Grove GSR Sensor is an electrodermal activity module designed to measure skin conductivity changes caused by emotional or physiological responses. It operates by detecting variations in galvanic skin response through two finger electrodes and provides an analog voltage output proportional to skin conductance. The module features adjustable sensitivity via an onboard potentiometer and supports both 3.3V and 5V systems. Built with the Grove interface for plug-and-play integration, it ensures reliable signal acquisition and simplified wiring. Suitable for emotion monitoring projects, biofeedback systems, and sleep quality studies. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family and get started to Grove your Idea.
