This module is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm. On board, digital output interface can be directly connected with the microcontroller IO.


  • Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm
  • Detection angle about 60 degrees, it is sensitive to the flame spectrum.
  • Accuracy adjustable
  • Operating voltage 3.3V ~ 5V
  • Output
    •  Analog voltage output
    •  Digital switch outputs (0 and 1)
  • With a mounting screw hole
  • 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
  • Size: 3.2 x 1.9cm
  • VCC: 3.3V ~ 5V
  • GND: GND
  • DO: board digital output interface (0 and 1)
  • AO: board analog output interface
