QB011 Flame Sensor

1.Product Introduction


The flame sensor can detect light sources with wavelengths ranging from 760 nm to 1100 nm to detect fire sources or other radiation sources. Its working principle is based on the flame in the combustion process, will emit a specific frequency of infrared radiation and visible light, using a special infrared receiver tube to capture the infrared wavelength in the flame to detect the existence of flame.

Application reference: fire extinguishing robot, flame alarm, etc.

2.Parameter Specification

Parameter Value/Representation
Operating voltage 3.3~5V
Operating temperature -10°C~+60°C
Wavelength 760nm~1100nm
Default output level High level
Output signal Digital signal
Size 3.16cm*2.38cm

3.Wiring Diagram

Flame Sensor UNO
S Digital Pin 7

4.Sample Code

void setup() {
  pinMode(7,INPUT);//The signal pin of the flame sensor is connected to the 7-pin of the arduino controller board
  Serial.begin(9600);//Serial port initialization, baud rate 9600
void loop() {
  Serial.println(digitalRead(7));//The serial port displays the detection value of the flame sensor in real time

5.Test Result

After uploading the code to the controller board, open the serial port monitor of the Arduino IDE, set the baud rate to 9600, and switch to the scroll mode.

When there is a flame in front of the flame sensor, the sensor returns data 1; When there is no flame in front of the flame sensor, the sensor returns the data 0.
