Flame Sensor Arduino Compatible

Arduino Compatible ARD2 Flame Sensor


1 $5.95


This Arduino compatible Flame Sensor is sensitive to flame or other light sources of the wavelength in the range of 760nm-1100nm. Usually used as a flame alarm. Its on-board, digital output interface can be directly connected with the microcontroller IO.

Test Code

int Led = 13; // define LED Interface
int buttonpin = 3; // define the flame sensor interface
int analog = A3; // define the flame sensor interface
int val; // define numeric variables val
float sensor; //read analog value

void setup () {
pinMode(Led, OUTPUT); // define LED as output interface
pinMode (buttonpin, INPUT); // output interface defines the flame sensor
pinMode (analog, INPUT); // output interface defines the flame sensor

void loop () {
sensor = analogRead(analog);
Serial.println(sensor); // display temperature
val = digitalRead (buttonpin); // digital interface will be assigned a value of 3 to read val
// When the flame sensor detects a signal, LED flashes
if (val == HIGH) {
digitalWrite (Led, HIGH);
else {
digitalWrite (Led, LOW);
