LM393 3 Pin IR Flame Detection Sensor Module | Fire Detector Infrared Receiver Module for Arduino

 

 

 

Code:

 //Arduino Flame Sensor
const int flamePin = 11;
int Flame = HIGH;
int redled = 13;
int Yellowled = 6;
void setup()
{
  pinMode(redled, OUTPUT);
  pinMode(Yellowled, OUTPUT);
  pinMode(flamePin, INPUT);
}
void loop()
{
  Flame = digitalRead(flamePin);
  if (Flame== LOW)
  {
    digitalWrite(redled, HIGH);
    digitalWrite(Yellowled, LOW);
  }
  else
  {
    digitalWrite(Yellowled, HIGH);
    digitalWrite(redled, LOW);
  }
}
