This flame sensor can be used to detect fire or other lights whose wavelength stands at 760 nm ~ 1100 nm. In the fire-fighting robot game, the flame plays an important role in the probe, which can be used as the robot's eyes to find fire source.
  • Supply Voltage: 3.3V to 5V
  • Detection range: 20cm (4.8V) ~ 100cm (1V)
  • Rang of Spectral Bandwidth: 760nm to 1100nm
  • Operating temperature: -25 to 85
  • Interface: digital
Sample code:
const int flamePin = 2; // the number of the flame pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int State = 0; // variable for reading status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(flamePin, INPUT);
void loop(){
// read the state of the value:
State = digitalRead(flamePin);
if (State == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
else {
// turn LED off:
digitalWrite(ledPin, LOW);
