Introduction: Fire Detection Alarm Arduino and Flame Sensor
In this blog I have shown you how to built fire detection alarm system using Arduino
Step 1: Get the Required Components
1. Arduino Uno
2. Breadboard
3. Led for Indicator (optional)
4.buzzer
5. Jumper wires
6. USB cable
Step 2:
Step 3: Connections
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
Step 4: Flame Sensor Arduino Code
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);
}
}
Step 5:
