Code snippet #1

Plain text
int HIH4000_Pin = A0; //analog pin 0

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

void loop(){

  //To properly caculate relative humidity, we need the temperature.
  float relativeHumidity  = analogRead(HIH4000_Pin);

 float av=0.0048875*relativeHumidity;
 
  float res=(av-0.86)/0.03;
Serial.println(res);
  delay(250); //just here to slow it down so you can read it
}
