Working Principle
The flame sensor use the IR sensor which is sensitive to the wavelength above 760nm. When it point to the flame source, the strong IR light will be catch by the IR sensor, it will change the output voltage of sensor, if the value pass threshold, which means the flame was detected.
Operate voltage: 3.3/5V
Interface: Analog
Sensitive spectrum wavelength: 760nm and above
Detection range: < 100 cm
Output voltage: 0 (no flame detected) ~ Operate voltage (flame detected with max intensity)
