EMG detector is a bridge that connects the human body with electrical currents. The sensor gathers small muscle signals and then processes them with 2nd amplifier and filter, the output signal can be recognized by Arduino. You can add this signal to your control system. In standby mode, the output voltage is 1.5V. When detecting muscle activity, the output signal rises up, the maximum voltage is 3.3V. You can use this sensor in a 3.3V or 5V system.
Electromyography (EMG) is a science that originated in Europe and the United States and began to be used in clinical practice abroad in the 1950s and in China around the 1980s. It is now recognized as an extension of clinical examination of neuromuscular diseases and can provide important information for the determination of the localization, characteristics, and degree of lesions of neuromuscular diseases in clinical diagnosis. Histochemistry, molecular biology, genetic testing, and imaging cannot replace the examination techniques.
