Introduction

Flame Sensor module can be used to detect fire source or other light sources of the wave length in the range of 760nm - 1100 nm. It is based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. Due to its black epoxy, the sensor is sensitive to infrared radiation. It can be used as a robot’s eyes to find the fire source. When detected the flame, LED will light and D0 output low voltage level.

Tip: light it with lamp won’t have any react unless you show him the flame, his name is flame sensor module.

Digital/Analog output

On-board LM393 chip

Usage

The module is mainly used to detect the infrared light. It outputs digital signal 0 or 1 through a Comparator output. The output value will be 0 when infrared light is detected. And the sensitivity is adjustable by the precision potentiometer.

1. Connect the module to the Arduino/Catduino.

2.Connect Arduino or Catduino to PC by using a USB cable.

3.Copy and paste code below to a new Arduino sketch, upload.

[code]

/*

 flame sensor connects to the analog pin 5 of Catuino.

 led connect to pin 2 of Catduino.

 */

int sensor=A5;    //Define the analog pin 5 as flame sensor.

int led=2;        //Define the pin 2 as led.

void setup() {

  pinMode(sensor, INPUT);  //Flame sensor is input.

  pinMode(led, OUTPUT);    //Led is output.

  Serial.begin(9600);     //Initial serial baud rate of 9600.

}

void loop() {

  int sensor_value=analogRead(sensor);

  int lightIntensity=map(sensor_value, 0, 1023, 0, 255);

  analogWrite(led,lightIntensity);

  Serial.print("sensor_value=");

  Serial.println(sensor_value);

  Serial.print("lightIntensity=");

  Serial.println(lightIntensity);

  delay(500);   //Delay half of a second.

}

[/code]

The LED will light up when there is infrared light who's wave length is in the range of 760- 1100mm.
