Me Flame Sensor can be used to detect fire source or light source with wavelength in the range of 760 nm to 1100 nm. Its detection angle is up to 60 degrees, and detection accuracy can be adjusted. When the flame is detected, its blue indicator will light on. It can be applied to the safety monitoring projects such as fire-fighting robot and flame.

[modifier] Principle analysis

The flame is composed of various combustion products, intermediates, high temperature gases, hydrocarbons, and high temperature solid particles (mainly the inorganic materials). The thermal radiation of the flame has gas emission with discrete spectrum and solid radiation with continuous spectrum. The radiation intensity and wavelength distribution of flame varies from burning objects. Generally the near-infrared light of flame has great radiation intensity. Me Flame Sensor is made on the basis of this feature.
