It is my first post here and I would like to introduce myself, I’m an Audio Engineer, currently studying Electronics with a lot of interest in measuring human emotions.
I’m getting together a EEG setup which I would like to compliment with an GSR sensor.
I got myself the Grove GSR sensor but because of my limited knowledge in programming I’m struggling to get it working properly.
I have a couple of questions and I hope someone will be able to help me here.
I’m able to get a raw GSR output into the Arduiono via the AnalogReadSerial, however the signal I’m getting is a skin resistance read, I would like to convert it into a conductance reading which I know is 1/R.
How would I express that in Arduino code?
My next question is about the unit conversion, standard unit for skin conductance is micro Siemens, how would I be able to code the arduiono to display the reading in this unit?
And finally I would like to use Processing to display my signal. I’m just looking for a simple visual graph which I can then modify to suit my needs.
I appreciate any help!
