EASY plug Flame Sensor Module



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.
Note: this module needs to be used together with EASY plug control board.

  • Detection range: 500px (4.8V) ~ 2500px (1V)
  • Rang of Spectral Bandwidth: 760nm to 1100nm
  • Operating temperature: -25℃to 85℃
  • Sensor type: digital
  • Size: 49*16.7mm
  • Weight: 6g

Connection Diagram


Sample Code

const int flamePin = 12;     // 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);
