Description

The EMG Muscle Activity Sensor Module is a compact bio-signal acquisition board designed to measure and amplify electrical activity generated by skeletal muscles (Electromyography signals). It detects subtle electrical potentials produced during muscle contraction and converts them into an analog output signal that can be read by microcontrollers such as Arduino, ESP32, Raspberry Pi, or other development boards.

This module is ideal for robotics control, prosthetics research, biomedical projects, gesture recognition systems, and human-machine interface applications.
