Technical summary
The electromyogram (EMG), the measurement of muscle activity, has traditionally been used in medical research; however, with shrinking yet more powerful microcontrollers and integrated circuits, EMG power Road and sensors can be used for various control systems.
This muscle sensor v3 measures, filters, rectifies and amplifies the electrical activity of a muscle and produces an analog output signal that can easily be read by a microcontroller, enabling new muscle-controlled interfaces for your projects.
EMG V3.0 muscle sensor module specifications and features:-
Electrode pad diameter: 52mm
Cable length: 50cm
Weight: 30gm.
Improved adjustable gain (more robust)
Built-in port for the new cables; connects to the board directly out of the box
Supply: a nominal dual 9V supply, the minimum voltage is 3.5V
Arduino-compatible
Wiring instructions:
To use this sensor, the user must have three electrodes connected to the subject's body.
The reference electrode must be placed on an inactive section of the body, such as the bony part of the elbow, the shin or the forearm. This electrode must be connected to the black or brown cable.
The two other electrodes must be placed along the muscle to be measured. The second electrode must be placed along the middle of the muscle; this electrode must be connected to the red cable.
The last electrode must be placed at the end of the muscle and connected to the blue cable.
Finally, connect the SIG pin to an analog input pin of your microcontroller and the GND pin to the ground pin of your microcontroller.
