Question

I need help with creating a arduino code using a GSR sensor that measures when a person is sweating or not.

Answer 1

GSR sensor has 4 pins:

black- ground

red- 5v

yellow-A0

white-NC

arduino code:-

const int GSR=A0;  //gsr yellow(data) pin should be connected to A0
int sensorValue=0;
int gsr_avg=0;

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

void loop()
{
  long j=0;
  for(int i=0;i<10;i++)           //Average the 10 measurements to remove the glitch
      {
      sensorValue=analogRead(GSR);
      j = j + sensorValue;
      delay(5);
      }
   gsr_avg = j/10;
  // In case you need to know or check the gsr avg remove the comments for the below line
  // Serial.println(gsr_avg);
   
   if(gsr_avg > 500)
   Serial.println("Sweating");
   else
   Serial.println("Not sweating")
}
