EMG Muscle Sensor for Arduino

Description

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.

Specifications :

• The diameter of the 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)

Wiring Instructions:

The user must have three electrodes connected to the subject’s body to use this sensor.

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.
