IR Flame Sensor Module RobotDYN

The Flame Sensor Module functions as an infrared receiver to detect fire or other infrared light sources. It uses a comparator IC to evaluate the infrared signal and provides a digital output. The output is LOW when a flame or infrared source is near and HIGH when it is distant. The sensor can detect light in the 760 to 1100 nanometer wavelength range and has a detection angle of approximately 60 degrees. The module sensitivity can be adjusted with a precision potentiometer. This sensor is suitable for a wide range of applications, including fire detection, industrial safety, robotics, IoT devices, and home automation. Caution should be taken to keep the sensor at a safe distance from high temperatures to avoid damage.

Arduino Test Code

 int flamePin = 4; // Connect digital output DO to Arduino pin 4 int ledPin = 13; // Onboard LED

void setup() {
pinMode(flamePin, INPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}

void loop() {
int sensorValue = digitalRead(flamePin);

if(sensorValue == LOW) { // Flame detected
digitalWrite(ledPin, HIGH);
Serial.println("Flame detected!");
} else {
digitalWrite(ledPin, LOW);
Serial.println("No flame");
}

delay(500); // Update every half second
}
