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.
Detects conductance of skin
Finger Straps for electrodes
Input Voltage: 5V/3.3V
Sensitivity adjustable via a potentiometer
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
It will be appreciated if you can help us improve the documents, add more demo code or tutorials. For technical support, please post your questions to our forum.
Yes, It is possible captured the output at regular intervals and logged in a file. But , We don't have a ready made library.
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.
Hello, the value is meanless and will not indicate a person's healthy.
You should calc the difference of values and get a result.
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
The output of GSR sensor is analog signal. More information you can refer to the wiki of GSR sensor.
