Examples

          


  1. int val;
    int tempPin = 1;
    
    void setup()
    {
    Serial.begin(9600);
    }
    void loop()
    {
    val = analogRead(tempPin);
    
    //float mv = (5.0 * val * 100)/1024;
    float mv = ( val/1024.0)*5000; 
    float cel = mv/10;
    //float cel = mv;
    
    float farh = (cel*9)/5 + 32;
    
    Serial.print("TEMPRATURE = ");
    Serial.print(cel);
    Serial.print("*C");
    Serial.println();
    delay(1000);
    
    /* uncomment this to get temperature in farenhite  */
    Serial.print("TEMPRATURE = ");
    Serial.print(farh);
    Serial.print("*F");
    Serial.println();
    
    
    
    
    }
          

Second Example

  1. float tempC; int reading; int tempPin = 0; void setup() { analogReference(INTERNAL); Serial.begin(9600); } void loop() { reading = analogRead(tempPin); tempC = reading / 9.31; Serial.println(tempC); delay(1000); }
