FLAME SENSOR 

                       Flame sensor is to detect and respond to the presence of flame (fire), allowing flame detection. A flame detector which often respond more accurately then heat or smoke sensor due to its mechanism it uses to detect flame. Flame sensors can detect explosions and fires by measuring the levels of radiation in the atmosphere.We can interface Flame sensor with Arduino to detect the detect the fire/flame.

    

Applications:

• Nuclear industry, pharmaceuticals, metal fabrication
• Agriculture, mining and power plants.
• Aircraft hangars, clothing dryers and high voltage equipment.
• Andustrial heating and drying systems, and furnaces.

Sample Project With Arduino:

                                    In this we going to turn ON the buzzer whenever the flame sensor detects or senses the fire(flame).And keeps the buzzer OFF when there is no detection flame.

Materials Required:

• ARDUINO UNO Board
• Flame Sensor
• Buzzer

Circuit:

                           

Code:

int Buzzer = 13;  // initializing buzzer in pin 13

int Flamesensor = 2;  // initializing flame sensor in pin 2

int Flame = LOW;  // HIGH when FLAME Exposed

void setup() {

  pinMode(Buzzer, OUTPUT);  // Declaring buzzer as output

  pinMode(Flamesensor, INPUT);  // Declaring Flame sensor as input

  Serial.begin(9600);  //Enabling Serial monitor

  }

void loop() {

  Flame = digitalRead(Flamesensor);  // Reading the value of sensor and storing in a variable

  if (Flame== HIGH) {  // checking the condition for the presence of flame

   Serial.println("HIGH FLAME");  // printing on serial monitor as HIGH FLAME

    digitalWrite(Buzzer, HIGH);  // Buzzer is turned HIGH when there is flame

  }

  else  {

    Serial.println("NO FLAME");  // if flame is not there,printing on serial monitor

    digitalWrite(Buzzer, LOW);  //Buzzer is turned LOW when there is no flame

  } 

}
