By detecting the electromyogram (EMG) measuring muscle activity has traditionally been used in research. With the advent of shrinking but more powerful microcontrollers and integrated circuits EMG power the sensors can be used for various control systems. Sensor will measure filtering rectifying electrical activity of the muscle output 0-Vs volts the output size to take depending on the amount of muscle activity is selected. Easy to use controller to detect muscle activity Compact designed for Microcontrollers Send data Breadboard compatible.
