If you are wandering to make a device that is used to detect measure electrical activity on muscle. then you will need sensors, So, you can buy them at a reasonable price.
The Advance Technologies EMG Muscle Sensor V3.0 With Cable And Electrodes will measure the filtered and rectified electrical activity of a muscle outputting 0-Vs Volts depending on the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. Power supply voltage: min. +-3.5V.
This Muscle Sensor v3 from Advancer Technologies 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 novel, muscle-controlled interfaces for your projects.
Getting Started Using Two 9V Batteries
Go through User Manual for details Stepwise description.
- The diameter of Electrode Pad: 52 mm
- Cable Length: 2 feet
- Weight: 30gm.
- Improved adjustable gain (more rugged)
- Onboard port for our new cables
- Connects to the board straight out of the box
- The reduced voltage needed (+-3.5V)
- To use this sensor, the user must have three electrodes connected to the subject’s body.
- The reference electrode should be placed on an inactive section of the body, such as the bony portion of the elbow, shin, or forearm. This electrode should be connected to the black or brown cable.
- The two other electrodes should be placed along the muscle selected to be measured. The second electrode should be placed along the mid-length of the muscle; this electrode should be connected to the red cable.
- The last electrode should be placed at the end of the muscle and connected to the blue cable.
- Finally, connect pin SIG to an analog input pin of your microcontroller and the GND pin to the ground pin on your microcontroller.
WARNING: As an inherent risk associated with electrical component work, improper use of this sensor could cause harm to the subject. If underage, do not use without adult supervision.
WARNING: This sensor is not intended for use in the diagnosis of a disease or other conditions, or in the cure, mitigation treatment, or prevention of disease, in a man or other animals.
