PRODUCT DETAILS
EMG detector is a bridge connects human body and electrical, the sensor gathers small muscle signal then process with 2th amplify and filter, the output signal can be recognized by Arduino. You can add this signal into your control system. Note: The sensor cannot be used for medical purposes.
In standby mode, the output voltage is 1.5V. When detect muscle active, the output signal rise up, the maximum voltage is 3.3V. You can use this sensor in 3.3V or 5V system.
Features
Grove Compatible
3.5mm Connector
6 Disposable Surface Electrodes
Power supply voltage: 3.3V-5V
1000mm Cable Leads
No additional power supply
Move
When finish downloading demo code, it'll take about 5s to initialize, you should keep static when initializing.
You can see that when initializing, the Led Bar will go form level 10 to level 0. When Led Bar All off, you can move now.
When you are moving, you can find that the level of Led Bar will change.

from order viewThe detectors are excellent. I ordered 10 items and all of them provide the signal that is good enough to detect any activity (I've tested them for upper-limb movements). Also, it is very suitable to use them with Grove Base shield for Arduino.
But I encountered some issues with the doc - initially, we got stuck on determining which of the wired electrodes is a reference electrode. The documentation does not give any information, except for one photo with electrode placement. But as I found out with the help of a multimeter, the black wire is a reference (or GND), the red one is left channel and the white is right. With such a configuration I was able to acquire a good signal. But in the image in the doc there is a red wire that seems to be a reference, and I suppose this is wrong, also we weren't able to acquire a good signal using such placement. -

We confirm the Grove-EMG Detector can be used along with a GrovePi+ and a Raspberry Pi2.
