Flame Detection with Flame Sensor

Objective

This experiment demonstrates how to detect flame using a flame sensor, which can be used for fire detection and safety systems.

Required Components

• Flame Sensor
• Arduino Board (e.g., Arduino Uno)
• Jumper wires
• Breadboard
• Arduino IDE (for programming)

Working Principle

The flame sensor detects infrared radiation from a flame or fire. When exposed to a flame, the sensor detects changes in the IR spectrum and sends an output to the microcontroller.

Circuit Diagram

Follow these steps to wire the flame sensor:

• Connect the VCC pin of the sensor to the 5V pin on the Arduino.
• Connect the GND pin of the sensor to the GND pin on the Arduino.
• Connect the signal pin of the sensor to digital pin 2 on the Arduino.

Arduino Code

/*
 * Flame Detection using Flame Sensor
 * This code detects the presence of a flame and outputs the result to the serial monitor.
 */

const int flamePin = 2;  // Flame sensor connected to digital pin 2
int flameState = 0;

void setup() {
    Serial.begin(9600);  // Initialize serial communication
    pinMode(flamePin, INPUT);  // Set the flame sensor pin as input
}

void loop() {
    // Read the flame sensor
    flameState = digitalRead(flamePin);

    // If the flame is detected
    if (flameState == HIGH) {
        Serial.println("Flame Detected!");
    } else {
        Serial.println("No Flame.");
    }

    delay(500);  // Wait for 0.5 seconds
}
            

Results

The serial monitor will display "Flame Detected!" when the sensor detects a flame and "No Flame" when it doesn't.

Applications

• Fire safety systems
• Flame detection in industrial areas
• Robotics for fire fighting applications

Conclusion

The flame sensor is an essential tool for detecting fires, with applications in fire safety, industrial safety, and robotics for fire fighting.
