Description: 1. CJMCU-6701 is an Analog Skin Sensor Module using GSR (Galvanic Skin Response) technology, which is an input device for detecting changes in electrical conductance between the skin and a reference electrode. 2. Interface: It communicates through an SPI interface (Serial Peripheral Interface), enabling easy connection to microcontrollers and development boards like Arduino and Raspberry Pi. 3. Voltage Compatibility: The module supports both 3.3V and 5V power supplies, making it suitable for a wide range of projects. 4. Analog Output: This sensor module generates an analog output voltage (0-5V) proportional to the electrical conductance changes, allowing direct readings and interpretation without conversion. 5. Sensitivity Adjustment: An external resistor can be connected for adjusting sensitivity levels, providing customization depending on user requirements or application scenarios. 6. Application: GSR sensors like CJMCU-6701 are commonly used in human-computer interaction proj
