EMG Muscle Sensor Module

The Arduino Muscle Signal Sensor – EMG Module is an analog front-end board designed to measure electrical activity generated by muscle contractions. It detects electromyography (EMG) signals, amplifies, filters, and rectifies them to provide a variable analog output proportional to muscle activity. The module operates using a dual power supply configuration starting from ±3.5 V up to ±9 V, ensuring stable signal conditioning and reduced noise. Built for reliable bio-signal acquisition, it is suitable for research, prosthetics control, human-machine interfaces, and robotics applications.
