Introduction

In this article, I will explain about connecting the Flame Sensor with an Android app.
When the flame is detected, it will send the message to the app.

Connection

Step 1

Connection from the Sensor to the Board.

Step 2

Connection from the Bluetooth to the Board.

Programming

const int AOUTpin = A0; //the AOUT
const int ledPin = 13; //the anode of the LED connects to digital pin D13 of the arduino
int limit;
int value;
void setup()
{
Serial.begin(9600);
//sets the baud rate pinMode(DOUTpin, INPUT);
//sets the pin as an input to the arduino pinMode(ledPin, OUTPUT);
//sets the pin as an output of the arduino
}
void loop()
{
value = analogRead(AOUTpin); //
limit = digitalRead(DOUTpin); //
Serial.print("Fire value: ");
Serial.println(value); //prints the CO value
Serial.print("Level: ");
Serial.print(limit); //prints the limit reached as either LOW or HIGH (above or underneath)
delay(100);
if (limit == HIGH)
{
Serial.println("fire dected");
}
else
{
Serial.println("Fire not dected");
}
}
