OYMotion Analog EMG Muscle Sensor

The OYMotion Analog EMG Sensor is a surface electromyography module designed to detect and amplify muscle electrical activity for research and control applications. It integrates differential input, analog filtering, and 1000× signal amplification to accurately process sEMG signals within ±1.5 mV. The module outputs a 0–3.0 V analog signal referenced at 1.5 V, enabling direct interfacing with microcontrollers such as Arduino. Designed for stable and low-noise performance, it supports both static and dynamic muscle monitoring. Suitable for biomedical research, human-computer interaction, and prosthetic control development.
