Hello guys. I'm doing a simple prototype for a scholar project with Arduino. Detects fire by the ambient light sensor DFR0026 (I'm testing it with a lighter flame at 5cm aprox.). Now I want to use a IR Bandpass Filter to make just the lighter flame increase the value from the DFR0026, ignoring all t…

A common 5mm black IR LED might be sensitive enough for a flame at 5cm.
