      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.


      Features

      • Detects conductance of skin

      • Finger Straps for electrodes


      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.

      What is the actual output of the GSR sensor (in numerical terms) given that I wish to obtain the Skin Conductivity Level. Kindly I would appreciate some guidance. Thanks

      Hi there~ The output voltage is an analog singnal which reflects the resistance of hunman skin.Which follows the equation : Human Resistance = ((1024+2Serial_Port_Reading)10000)/(512-Serial_Port_Reading).If you want to know how this formula is derived,please check here ### https://www.seeed.cc/topic_detail.html?id=13059 ###Regards

      Is there an equation to convert from Human resistance to Skin Conductivity Level. Can you please guide me? Thanks.

      Hello~ OK,let me help you, please check the link below ### https://github.com/SeeedDocument/USB-CAN_Analyzer/raw/master/res/1122.png ###.Actually,you can google conductivity and resistance.So,if you want to use this sensor to measure the conductivity,you need to know the lenth and area of your skin.Regards

      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

      you can add an SD card component to arduino and write to there, then move the file anywhere.

      Is threshold 600 normal? I'm afraid it's bad.

      Is it compatible to PIC microcontroller?

      Hi~We have not tested it with PIC,but theoretically it is compatible.It's a digital sensor,you can read the data via any digital pins.But you need to code by youself.

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

      Hi there~ the value is affected by many factors,so the normal value is hard to say.In fact, what matters is the trend of data changes.Regards

      Hi there~ You can refer to the data sheet of the LM324 ### https://raw.githubusercontent.com/SeeedDocument/Grove-GSR_Sensor/master/res/Lm324.pdf ###.Besides,for this sensor we use 5V vcc,the output is an analog signal.Regards

      Hi, does this sensor use an exosomatic or an endosomatic smethod?That is: are you 1) passing an external current across the skin and measuring the resistance or are you 2) recording the skin potential without any external current? If the response is "1", what is the voltage applied between the two electrodes?

      Hi there~ Actually, it is "1",and the voltage is no more than 2.5V, you can refer to the .sch file here ### https://github.com/SeeedDocument/Grove-GSR_Sensor/raw/master/res/Grove%20-%20GSR_v1.2_SCH.pdf ###.Regards

      To possibly use this for scientific reasons I would need to have the output in Microsiemens (µS). Do you know how can I get it starting from your output?Thanks, Gianluca

      Hi there~First of all,we do not recommend using this sensor for scientific research.Second , the output of this sensor is human skin resistance.And follows the equation: follows the equation : Human Resistance = ((1024+2Serial_Port_Reading)10000)/(512-Serial_Port_Reading). Best regards
