ARDUINO SKETCH FOR FIRE SENSOR

////USE THIS CODE FOR FIRE SENSOR FOR BETTER RESULTS......

int val ;// define numeric variables val
float sensor; //read analoog value
void flamesensor()
{
  int sensorReading = analogRead(A5);
  // map the sensor range (four options):
  // ex: 'long int map(long int, long int, long int, long int, long int)'
 int range = map(sensorReading, sensorMin, sensorMax, 0, 3);
 
  // range value:
  switch (range) {
  case 0:    // A fire closer than 1.5 feet away.
    Serial.println("** Close Fire **");
    Serial.println(sensorReading);
    break;
  case 1:    // A fire between 1-3 feet away.
    Serial.println("** Distant Fire **");
    Serial.println(sensorReading);

    break;
  case 2:    // No fire detected.
    Serial.println("No Fire");
    Serial.println(sensorReading);

    break;
  }
  delay(5000);  // delay between reads
}
