Hello PeaceTsy,

Could you test the sensor with the KST example?

Regards.

Hello PeaceTsy,
did you manage to solve your problem? I'd also like to aks if ECG electrodes may be applied to measure EMG values.

Hello pmisiak,

yes you can use ECG electrodes to measure EMG values.

Hi everyone

I'm experiencing exactly the same problem with EMG measurement as edog.

In response to this problem, libelium-dev suggested replacing "delay (1)" with "delay (100)".

Does this mean that approx 10Hz is the upper limit of sampling frequency of EMG measuremnt by e-Health platform?

This sf seems unacceptably low for EMG measurement.

Hello PeaceTsy,

Please try to change this line:

Code:

delay(1); // wait for a millisecond

to:

Code:

delay(100);

Try and tell us your results.
