How to use the Infrared Flame Sensor with Arduino

INTRODUCTION

The IR (Infrared) flame detector/sensor is a device designed to detect and respond to the presence of a flame or fire.

APPLICATIONS

Can be used as a safety device to detect a flame and sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.

WIRING DIAGRAM

VCC – 5V

D0 – Digital Pin 2

GND -  GND

 

CODE

int SensorPin = 2;

void setup() {
  // set SensorPin as INPUT:
  Serial.begin(9600);
  pinMode(SensorPin, INPUT);
}

void loop() {
  // default mode for the sensor pin is HIGH. Here we are telling it
  // to do the opposite and print “fire detected” when sensor receives input
  // from a fire source:
  int buttonstate = digitalRead(SensorPin);
  if (buttonstate == LOW){
  Serial.println("fire detected");}
  if (buttonstate == HIGH){
  Serial.println("no fire detected");}
  
  delay(50);
}

END RESULT

Find a lighter or a light source and test out the sensor with the serial monitor.
