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.

Sensor and flame to keep a certain distance, to avoid high temperature damage sensor, the lighter test flame distance is 80 cm, the flame is bigger, test the farther the distance.

• 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
• Size : 4.5 x 1.5cm
• Operating voltage : 3.3V ~ 5V
• Output :
  • Analog voltage output
  • Digital switch outputs (0 and 1)
• 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.

Interface(4-wire) :

• VCC: 3.3V ~ 5V
• GND: GND
• DO: board digital output interface (0 and 1)
• AO: board analog output interface

Note:

• Please keep a distance with flame, high temperature maybe burn out the sensor module.
