Arduino Mega 2560 Project 13: Flame Sensor

Posted by Fiona Su on

Introduction:
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.
Specification:
  • 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
  • Size: 44*16.7mm
  • Weight: 4g

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); 
  }
}
