Flame Sensor Module Wavelength 760nm-1100nm

• Comparator chip LM393 ,it is stable.
• 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 
    DO digital switch outputs (0 and 1)
    AO analog voltage output
• power indicator and digital switch output indicator
• With a mounting screw hole
• PCB size: 3.1cm * 1.5cm
• Interface Description (4-wire)
  1 VCC -- 3.3V-5V voltage
  2 GND -- GND
  3 DO  -- board digital output interface (0 and 1)
  4 AO  -- board analog output interface

Introduction:

• This module is sensitive to the flame, but aslo can detect ordinary light. Usually used as a flame alarm.
• 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.
