EMG SENSOR

The EMG Muscle Sensor V3.0 measures, filters, rectifies, and amplifies the electrical activity of a muscle, producing an analog output (0V to Vs) readable by any microcontroller ADC. Includes cable and electrode pads. Adjustable gain for robust signal capture. Requires dual-supply power (±3.5V minimum, typically ±9V via two 9V batteries).

Warning: This sensor is NOT a medical device and is not intended for medical diagnosis or treatment. If underage, do not use without adult supervision.
