Product Description

        The 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.

This Flame Sensor Module is used to detect fire/flame source or other light sources of the wavelength in the range of 760nm – 1100 nm. It is based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. Due to its black epoxy, the sensor is sensitive to infrared radiation.
