I am trying to measure EMG Signals with an Arduino Uno for my Masters Thesis. I found this
wiring example and tried to reproduce it. I am using an old Plux emg sensor and I expected it to work similar to the Bitalino sensors, but I dont get a signal at all.
Apparently someone ripped off the plug of the eng sensor, so I compared the wires colors to a functioning sensor. I believe the correct wiring pattern is:
red = VCC
white = VOUT
black = VSS
shielding = GND
green = unused
I connected the emg sensor to the Arduino in the following way:
The output I get at A0 is a constant value around 152 (+/- 1), which is around 152/1034*5V = 0.74V.
I power the Arduino via USB from a Notebook that is not plugged in to AC.
I think the possible reasons why this fails are:
- my color pattern for the emg sensor is wrong
- my emg sensor is broken (since someone ripped off the plug this isnt very unlikely, is there a simple way to test it?)
- my circuit is somehow wrong, but i doubt Plux sensors need a different circuit than Bitalinos.
