Flame Sensor module
The Flame Sensor can detect flames in the 760 - 1100 nano meter wavelength range. Small flames like a lighter flame can be detected at roughly 0.8m. Detection angle is roughly 60 degrees and the sensor is particularly sensitive to the flame spectrum. An on board LM393 op amp is used as a comparator to adjust the sensitivity level. The sensor has a digital and analog output and sensitivity can be adjusted via the blue potentiometer.
Overview
Detect flame or wavelength range (approx): 760 nm to 1100 nm, lighter flame test distance is 80cm, the greater flame, the farther test distance
Detection angle is about 60 degree, particularly sensitive to flame photometry
