Description:
1.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.
Feature:
1.Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm
2.Detection angle about 60 degrees, it is sensitive to the flame spectrum.
3.Accuracy adjustable
4.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.
