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 ...

The easiest and cheapest way to detect thermal radiation is to use a flame sensor. In this tutorial, we will see how we can interface a flame sensor module with Arduino. Flame Sensor Module Pinout.

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 ...

Arduino based Fire Alarm – Circuit and Working. Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...
