Flame Sensor Module - ADIY

ADIY Flame Sensor Module can detect flames in the 760 – 1100 nanometer wavelength range. Small flames like a lighter flame can be detected at roughly 0.8m. The 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.
