Ks0036 keyestudio Flame Sensor

Introduction

This flame sensor can be used to detect fire or other lights with wavelength stands at 760nm ~ 1100nm.
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

Connection Diagram

Connect the D0 pin to digital 2, GND pin to GND port, VCC pin to 5V port.

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); 
}

Result

Done wiring and powered up, upload well the code to the board.
Then if you put a lighter close to the sensor, when the sensor detects the flame, another led on the sensor is turned on.
