Can detect the flame or wavelength at 760 nm to 760 nm range of light, the lighter the test flame distance is 80 cm, on the flame, the greater the distance test
The detection Angle of 60 degrees or so, particularly sensitive to the flame spectrum
The sensitivity adjustable digital potentiometer to adjust (blue)
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma
With adjustable precision potentiometer sensitivity adjustment
