EMG EB Muscle Sensor V1.2 Kit
By detecting EMG (EMG), measuring muscle activity have traditionally been used in medical research. However with smaller but more powerful microcontroller and the advent of integrated circuits , EMG sensor can be used for various control systems.
Sensor will measure the the electrical activity of the muscles of the rectifier output 0-Vs volts , the output value is depended on the amount of muscle activity .
It is very easy to use for Arduino controller detects muscle activity
