  GND	GND
  5V	VCC
  A0	Analog Output Pn

• Flame Sensor with Arduino

  Arduino	Flame Sensor
  GND	GND
  5V	VCC
  2	Digital Output

• Buzzer, LEDS with arduino

  Arduino	GND	UNO Pin No
  Buzzer	GND	8
  Green LED	GND	5
  Yellow LED	GND	6
  Red LED	GND	7

Code :

    void setup() {
    pinMode(2,INPUT);
    pinMode(A0,INPUT);
    
    pinMode(5,OUTPUT);
    pinMode(6,OUTPUT);
    pinMode(7,OUTPUT);
    
    Serial.begin(9600);
  }

  void loop() {
    int gas = analogRead(A0);
    int fire = digitalRead(2);
    if (gas >180 || fire ==0){
      digitalWrite(5,0);
    }else{
      digitalWrite(5,1);
    }
     
    if(gas > 180){
      Serial.print(gas);
      Serial.println(" Gas Smoke Detected");
      tone(8,1000);
      digitalWrite(6,1);
    }
    else{
      Serial.print(gas);
      Serial.println(" No Gas Smoke Detected");
      noTone(8);
      digitalWrite(6,0);
    }
    if (fire==0){
        Serial.println("Fire Detected");
        digitalWrite(7,1);
   
      }
    else{
        digitalWrite(7,0);
        Serial.println("No Fire Detected");
      }  
      delay(1000);
  }

Result When in Safe Condition

Result When in Lekage of Gas Detected

Result When in Fire or Flame Detected
