This is the Flame detection sensor its detect 60 degree angle spectral sensitivity of 720-1100nm. The spectral sensitivity of this sensor is optimized to detect emissions from naked flames. The output signal DO is pulled on a high state (active high) when a flame is detected. The switching threshold is adjustable via a preset adjustable POT. Analog for this sensor is available at pin A0 can be adjust to trigger on a specific values reads on analog.
These module use an infrared. It can detect infrared rays with wavelength mention above. A far infrared probe converts the strength charges of external infrared light into current charges then it converts analog quantities into digital. On this experiment we will used PIN D0 of the sensor to RPRI GPIO whether any flame exists. Just follow the schematics illustration below.
