Flame Detection Sensor Module is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm.


Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm. Detection point of about 60 degrees, particularly sensitive to the flame spectrum. Sensitivity is adjustable, stable performance.



  • Detection angle about 60 degrees, it is sensitive to the flame spectrum
  • Accuracy adjustable
  • Operating voltage 3.3V-5V
  • Output a. analog voltage outputb. digital switch outputs (0 and 1)
  • With a mounting screw holePCB size: 3cm * 1.6cm
  • Power indicator (red) and digital switch output indicator (green)
  • Comparator chip LM393 ,it is stable
  • Flame detection distance, lighter flame test can be triggered within 0.8m, if the intensity of flame is high , the detection distance will be increased
  • On board, digital output interface can be directly connected with the microcontroller IO
  • Please keep a distance with flame, high temperature maybe burn out the sensor module


Package Includes:

  • 1 x Flame Sensor Module
