Grove - GSR Sensor stands for galvanic skin response and it is a method of measuring the electrical conductance of the skin. It can be used to reflect human emotional activity. Features Direct Skin Conductance Measurement: Accurately captures real-time variations in skin electrical conductance, providing the essential raw data for analyzing Skin Conductance Response (SCR) and cognitive load. Raw Analog Output for Edge AI: Delivers pure, uncompressed analog voltage signals—ideal for ADC sampling, custom feature extraction, and training TinyML models for human-state sensing. Broad Platform Compatibility: Plug-and-play integration with 3.3V/5V hardware ecosystems, seamlessly supporting Seeed Studio XIAO, Arduino and Raspberry Pi (via ADC)for rapid prototyping. Adjustable Signal Gain: Features an onboard potentiometer to manually tune the analog output amplification. This prevents signal clipping and helps keep the readings centered within your MCU's ADC range across users with varying baseline skin resistance. Description When we are emotionally stressed or have strong expressions on the face, sympathetic activity increases and promotes the secretion of sweat glands, which increases the skin's electrical conductivity. Grove - GSR sensor or eda sensor allows you to spot such strong emotions by simply attaching two electrodes to two fingers on one hand. It is an interesting gear to create emotion-related projects like sleep quality monitors. In some galvanic skin response devices such as lie detectors, this scientific principle is also applied. 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. For all Grove users (especially beginners), we provide you with guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product. Application In the experiment, we inserted our fingers into the two electrode fingertips of the sensor and connected a Buzzer to the digital output of the seeeduino. During the test, the value detected by the sensor will continue to change within a certain range. When the tester takes a deep breath, the range of the fluctuation will suddenly increase and exceed the threshold we set, and then the buzzer will be triggered. Other Application TinyML Model Training: Capturing raw analog skin conductance data to train lightweight edge models for stress and cognitive load classification. State-Aware AI Agents: Serving as a physiological input layer for Large Language Models (LLMs) to prototype context-aware, adaptive AI assistants. Adaptive HCI Hardware: Prototyping experimental biofeedback interfaces, interactive smart peripherals, and emotion-responsive VR/gaming controllers. Rapid Biofeedback Prototyping: Utilizing standard ADC interfaces on microcontrollers (like ESP32/XIAO) for early-stage wearable and wellness tech development. STEM & Engineering Education: Providing an accessible analog module for teaching ADC sampling, digital signal processing (DSP), and fundamental human-state sensing.
