Flame Sensor Infrared Receiver Ignition Source Detection Module

Description

A flame sensor is a device that detects the presence of a flame or fire. It typically uses an infrared (IR) sensitive photodiode or phototransistor that can identify wavelengths produced by flames. Flame sensors are used in various applications, such as fire detection, security systems, and robotics.

Technical Specifications

• Operating Voltage Range: 3.6~5 VDC
• Average Current Consumption (mA): < 20 mA
• Field of view: 60°

D0	Pin 2

 

Sample code:

int flamePin = 2; // Digital pin connected to DO

int flameState;

 

void setup() {

  pinMode(flamePin, INPUT);

  Serial.begin(9600);

}

 

void loop() {

  flameState = digitalRead(flamePin);

  if (flameState == LOW) { // Flame detected (LOW due to active LOW signal)

    Serial.println("Flame detected!");

  } else {

    Serial.println("No flame detected.");

  }

  delay(500); // Delay for better readability
