Initialization: The Arduino initializes the pins for the flame sensor, built-in LED, and external LED, and begins serial communication. Flame Detection: The flame sensor reads the presence of a flame ...

The flame sensor detects the presence of fire or flame based on the Infrared (IR) wavelength emitted by the flame. It gives logic 1 as output if a flame is detected, otherwise, it gives logic 0 as ...
