As the picture showa, I want to know something about the Infrared Flame Sensor module. This sensor has a infrared receiver to detect the infrared generated from the flame. The output pin could either be digital or analog according differnent purpose,

 

As I want to build a firefighter bot in my final project, this flame sensor is extremely important for me to detect the fire flame. Since the sunlight has interference with the accuracy of the digital output of this sensor, I would like to use the analog pin to detect the candle flame.

 

I'll do some simple experiments on this sensor, like the control of the led or beeper, which I'll keep updating in the future exploration of my final project.
