Flame Detection System Using Arduino

A flame detection system using an Arduino UNO and a flame sensor. The system detects the presence of a flame and provides visual and serial output alerts.

When a flame is detected a warning message is printed to the Serial Monitor. When no flame is detected a corresponding message is printed to the Serial Monitor.

Components Needed

• Arduino UNO
• Flame Sensor
• Jumper Wires
• Power supply 12 v

Hardware Wiring Explanation:

Flame Sensor to Arduino:

Use the jumper wires to connect the flame sensor pins to the corresponding Arduino pins as outlined above.

Software (Arduino IDE):

Open the Arduino IDE on your computer.

Write or paste the program into the IDE.

Connect the Arduino board to your computer using a USB cable.

Select the correct board and port in the Arduino IDE under the Tools menu.

Upload the program to the Arduino.

Monitor the Output

Open the Serial Monitor in the Arduino IDE by selecting Tools - Serial Monitor.

Set the baud rate to 9600 in the Serial Monitor.

Observe the messages indicating whether a flame is detected or not.

Operation

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 (LOW signal indicates a flame).

If a flame is detected, both the built-in and external LEDs turn on, and a warning message is printed to the Serial Monitor.

If no flame is detected, both LEDs remain off, and a message indicating no flame is printed to the Serial Monitor.

Applications

This project can be used in various applications including:

By understanding the basics of how to interface and use a flame sensor with Arduino, you can expand this project to include more sophisticated functionalities such as sending alerts via SMS or email, activating alarms, or integrating with a home automation system for enhanced safety.
