Baby Introduction By detecting the electromyogram (EMG), measuring muscle activity has traditionally been used in research, however, With shrinking but more powerful microcontrollers and integrated circuits advent EMG power Road and 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. Material: ABS P o Color Easy to use controller detects muscle activity Baby characteristics Compact Designed for Microcontrollers Send data Breadboard compatible Power supply voltage: + -9V dual power supply, minimum + -3.5V Package Contents: 1 x muscle sensor board 1 x professional EMG cable 3 x disposable surface electrode Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
