Description
GSR stands for galvanic skin response, is a method of measuring the electrical conductance of
the skin. Strong emotion can cause stimulus to your sympathetic nervous system, resulting
more sweat being secreted by the sweat glands.
Grove - GSR allows you to spot such strong emotions by simple attaching two electrodes to
two fingers on one hand. It an interesting gear to create emotion related projects like sleep
quality monitor.
Note: This device is not medical device.
KEY FEATURES
Detects conductance of skin
Finger Straps for electrodes
TECHNICAL SPECIFICATIONS
Input Voltage: 5V/3.3V
Sensitivity adjustable via a potentiometer

I want the output to be captured at regular intervals and logged in a file (such as CSV). Is it possible to do
this? Thanks. - Kanad

So, what is the normal GSR value of the skin for a healthy person?

Yes, It is possible captured the output at regular intervals and logged in a file. But , We don't have a ready made
library.
Kavi,Not sure I fully understand.Here is what I am trying to accomplish -- I would like to collect GSR data from
finger electrodes at regular intervals for a few hours (have them stored in the local Arduino module), and then
hook the Arduino module through the Uno board to a PC after the end of the data collection for offline data
analysis. I am NOT interested in doing real-time data analysis and visualization as the data is being collected.
Please explain how to accomplish data collection/data logging for a few hours followed by offline data analysis
using a PC. Thanks,Kanad
@kanadc you can add an SD card component to arduino and write to there, then move the file anywhere.

Hello, the value is meanless and will not indicate a person's healthy. You should calc the difference of values
and get a result.Thanks.

Hi.I would like to know what resistance value had the potentiometer when the sample data shown in the
wiki was taken. Thanks J.C.

Hi,I am wondering, what is the output of Grove analogue sensors? Is it continuous analogue voltage or
pwm? We use our own controller, which supplies 5V DC for the sensors and reads the analogue data. Will
it work with your grove analogue sensors
