Grove GSR - Skin Sensor Module (Skin Resistance Conductivity) - แท้จาก SeeedStudio

Specification

Getting Started

Hardware

• Step 1. We need to prepare the below stuffs:

Seeeduino V4.2	Base Shield	Grove - GSR

• Step 2. Connect the Grove-GSR to A0 on Base Shield.
• Step 3. Plug the base Shield into Seeeduino-V4.2.
• Step 4. Connect Seeeduino-V4.2 to PC by using a USB cable.

Software

• Step 1. Copy the code into Arduino IDE and upload.

const int GSR=A0;
int sensorValue=0;
int gsr_average=0;

void setup(){
Serial.begin(9600);
}

void loop(){
long sum=0;
for(int i=0;i<10;i++) //Average the 10 measurements to remove the glitch
{
sensorValue=analogRead(GSR);
sum += sensorValue;
delay(5);
}
gsr_average = sum/10;
Serial.println(gsr_average);
}

• Step 2. Wear the GSR sensor
• Step 3. Click the Tools-> Serial Plotter from Arduino IDE
• Step 4. We will see the below graph. Please deep breath and see the trends.

Human Resistance = ((1024+2Serial_Port_Reading)10000)/(512-Serial_Port_Reading), unit is ohm, Serial_Port_Reading is the value display on Serial Port(between 0~1023)
