Product Description
In medical research, measuring the activity, contraction and expansion of muscles is important. The EMG muscle sensor measures the muscle activity and produces a signal to show the amount of expansion and contraction. Therefore, the output depends on the amount of activity in the selected muscle.
Traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems.
Instruction:
- Connect the power supply (two 9V batteries)
- Connect the positive terminal of the first 9V battery to the +Vs pin on your sensor.
- Connect the negative terminal of the first 9V battery to the positive terminal of the second 9V battery. Then connect to the GND pin on your sensor.
- Connect the negative terminal of the second 9V battery to the –Vs pin of your sensor.
- Connect the electrodes
- After determining which muscle group you want to target (e.g. bicep, forearm, calf), clean the skin thoroughly.
- Place one electrode in the middle of the muscle body, connect this electrode to the RED Cable’s snap connector.
- Place a second electrode at one end of the muscle body, connect this electrode to the Blue Cable’s snap connector.
- Place a third electrode on a bony or non‐muscular part of your body near the targeted muscle, connect this electrode to the Black Cable’s snap connector.
- Connect to a Microcontroller (e.g. Arduino)
- Connect the SIG pin of your sensor to an Analog pin on the Arduino (e.g. A0)
- Connect the GND pin of your sensor to a GND pin on the Arduino.
