Arduino Flame Detection Sensor Module

Our home task was to find out what the sensor does. I got flame detection sensor module which detects infrared rays. We connected one led to the sensor, so it would set on if the sensor detects infrared. We had a remote control which of course works with infrared. Always when we pushed a button the led turned on. It worked pretty well.

The code:

/*SENSOR PINOUT:

PIN 1: Analogue out
PIN 2: Ground
PIN 3: +5V
PIN 4: Digital out

/* Select the input pin for the flame detectors analogue output. */
#define FLAME_DETECT_ANA A0

/* Select the input pin for the flame detectors digital output. */
#define FLAME_DETC_DIO 2
int led = 8;


/* Initialise serial and DIO */
void setup()
{
/* Setup the serial port for displaying the status of the sensor */
Serial.begin(9600);
pinMode(led, OUTPUT);
/* Configure the DIO pin the sensors digital output will be connected to */
pinMode(FLAME_DETC_DIO, INPUT);
}


/* Main program loop */
void loop()
{
/* Read the sensors analogue output and send it to the serial port */
Serial.print("Sensor Value: ");
Serial.print(analogRead(FLAME_DETECT_ANA));

/* Read the status of the sensors digital output and if it is high
then send an alert to the UART */
if (digitalRead(FLAME_DETC_DIO))
{
Serial.println(" FLAME DETECTED!");
digitalWrite(led, HIGH);
delay(1000);
digitalWrite(led, LOW);

}else
{
Serial.println();
digitalWrite(led, LOW);

}

}
