Fire Detection Alarm Arduino and Flame Sensor

In this blog I have shown you how to built fire detection alarm system using Arduino

1. Arduino Uno

2. Breadboard

3. Led for Indicator (optional)

4.buzzer

5. Jumper wires

6. USB cable

So Here, Lets Make Connections With Arduino Uno and Flame SensorConnect flame sensor

VCC = 5v

GND = Gnd

Flamse Sensor Dout = 8

Buzzer = 12

Red Led = 5

Green Led = 6

int flamesensor =8;
int buzzer = 12;
int redled = 5;
int greenled = 6;
int flame = LOW;
void setup() {
Serial.begin(9600);
pinMode(flamesensor,INPUT);
pinMode(buzzer,OUTPUT);
pinMode(redled,OUTPUT);
pinMode(greenled,OUTPUT);
}
void loop() {
flame = digitalRead(flamesensor);
if (flame == LOW){
Serial.println("Fire Occured Please Be Safe");
digitalWrite(redled,HIGH);
digitalWrite(greenled,LOW);
; digitalWrite(buzzer,HIGH);
delay(100);
digitalWrite(buzzer,LOW)
delay(100);
}
else{
digitalWrite(redled,LOW);
digitalWrite(greenled,HIGH);
digitalWrite(buzzer,LOW);
}
}
