How to use the 5-way Flame sensor module with an Arduino | 5 channel Flame sensor module with Arduino

Hello and welcome back. In this tutorial, we will learn how to use the 5-way Flame sensor module with an Arduino. For this project, I have used 5 LEDs to visually indicate when the sensor detects fire. However, you can test the sensor without using LEDs if you prefer. Also, I used an Arduino UNO board, but you can use any Arduino board you like. This knowledge can be applied to create fire alarm systems, fire-fighting robots, and more.

5-way Flame sensor module

This sensor module has 5 infrared (IR) receiver LEDs. Typically, a single flame sensor can detect flames within a 30-degree range, but this module can detect flames over a range of more than 120 degrees. It is designed to detect flame wavelengths in the range of 700-1100 nm, which falls within the short-wave near-infrared (SW-NIR) spectrum. The module also includes built-in LEDs to indicate the presence of flames, which is a useful feature. Also, we can get the 5 digital and analog signals using this sensor module. Additionally, it has a potentiometer that lets you adjust the sensitivity range of the sensor to better suit your needs. Also, this Flame sensor module operates within a voltage range of 3.3V to 9V, making it compatible with different power sources.

Step 1

Firstly, identify these components.

Step 2

Secondly, connect the flame sensor module to the Arduino board. For that, use the circuit diagram below.

Step 3

Thirdly, place the LEDs on the breadboard. Please connect the cathode pins to the breadboard cathode rail. Then connect the one-by-one resistors to the anode pins.

Step 4

Next, connect these resistor legs to the Arduino board. For that, I used digital pins D7 to D11. Please connect the Arduino board power pins (5v, GND) to the breadboard power rails. Then, connect the Arduino board to the computer.

Step 5

Now copy and paste the following program to the Arduino IDE.
