Things used in this project

Hardware components

Arduino UNO

This is our programmer board.

5 mm LED: Red

This will turn on when there is a fire.

5 mm LED: Green

This will switch on when there is no fire.

IR fire sensor

This will detect our fire

Jumper wires (generic)

No circuit is complete without jumpers!

Buzzer

This is our alarm

Software apps and online services

Arduino IDE

Story

Today I am back with another project which is like a fire detector and is very accurate. So, the video for this project is found here:

keep in mind that this video is only accessible by link

Diagram (simplified)

This is what the diagram would have looked like in a simple view:

Requirements

There are certain requirements depending on what tools you have. The first one is that your fire sensor must support a digital output. To check if yours does support one, try seeing if yours has a pin that is labeled 'D0'. The second requirement is that you need to have a IR fire sensor. To check if yours is, your fire sensor should not look like that:

One Way DC 12V Flame Sensor Relay Module

Or that:

5 Way Flame Sensor Module

But it should look something like that:

IR flame sensor

Code

Code

//Arduino Flame Sensor
const int buzzerPin = 12;
const int flamePin = 11;
int Flame = HIGH;
int redled = 5;
int greenled = 6;
void setup() 
{
  pinMode(buzzerPin, OUTPUT);
  pinMode(redled, OUTPUT);
  pinMode(greenled, OUTPUT);

  pinMode(flamePin, INPUT);
  Serial.begin(9600);
}

void loop() 
{
  Flame = digitalRead(flamePin);
  if (Flame== LOW)
  {
    digitalWrite(buzzerPin, HIGH);
    digitalWrite(redled, HIGH);
    digitalWrite(greenled, LOW);
  }
  else
  {
    digitalWrite(buzzerPin, LOW);
    digitalWrite(greenled, HIGH);
    digitalWrite(redled, LOW);
  }
}
