CJMCU-6701 GSR Skin Sensor Module Analog SPI 3.3V/5V (Galvanic Skin Response Sensor for Arduino)

The CJMCU-6701 GSR Skin Sensor Module is a physiological sensing module designed to measure Galvanic Skin Response (GSR) by detecting changes in the electrical conductivity of human skin. Variations in skin conductivity are influenced by sweat gland activity and can be used in biofeedback, stress monitoring, and physiological research. The module supports both analog output and SPI digital communication, making it easy to interface with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms.

Operating from 3.3V or 5V DC, the module offers stable and reliable measurements for wearable electronics, health monitoring systems, emotion detection experiments, human-computer interaction, and educational research projects.
