Flame sensor

Can detect a flame or light of 760 ~ 1100nm wavelength, 80cm brighter flame test distance, for the larger flame, the test more remote.
The detection angle is about 60 degrees, especially sensitive to the flame spectrum.
Sensitivity is adjustable (indicated by the blue digital potentiometer setting).
Comparator output, signal clean, good waveform, strong driving ability, more than 15mA.
With adjustable precision potentiometer for sensitivity adjustment.
