Sanki Notes




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);
}
