Intelligent flame detection system with Arduino

Presentation of the flame detection system

A flame detection system is a device or system that is used to detect the presence of a fire or flame. These systems are used in a variety of settings, such as buildings, industrial facilities, and vehicles, to provide early warning of a potential fire and to help prevent damage and loss of life.

There are several types of flame detection systems, including:

  • Optical flame detectors: These use a sensor to detect the presence of a flame by analyzing the light emitted by the flame. They can be sensitive to specific wavelengths of light and can detect flames at a distance.
  • Infrared flame detectors: These use infrared sensors to detect the presence of a flame. They are sensitive to the heat emitted by a flame, and can detect flames at a distance.
  • UV flame detectors: These use ultraviolet sensors to detect the presence of a flame. They are sensitive to the ultraviolet radiation emitted by a flame, and can detect flames at a distance.
  • Thermal flame detectors: These use temperature sensors to detect the presence of a flame. They are sensitive to the heat emitted by a flame, and can detect flames at a distance.

Some flame detection systems use multiple sensors to detect the presence of a flame, and to reduce the likelihood of false alarms. They are often integrated with fire alarm systems and can trigger alarms, activate sprinklers, and notify emergency responders in case of a fire.

Flame detection systems can be integrated with IoT (Internet of Things) technology to provide remote monitoring and control capabilities. This allows users to monitor the status of the flame detection system and receive alerts in case of a fire, even when they are not physically present.

IoT-enabled flame detection systems typically use sensors to detect the presence of a flame and then use a communication module such as Wi-Fi or cellular to send the data to a cloud-based platform or a remote server. This data can then be accessed and analyzed using a web or mobile application.

In addition to monitoring and alerting, IoT-enabled flame detection systems can also be used to control other devices or systems in response to a fire, such as shutting off gas valves, activating sprinklers, or notifying emergency responders.

IoT-enabled flame detection systems can also provide additional features such as real-time monitoring, historical data analysis, and remote access, which can help improve the overall safety and security of a facility.

Presentation of Arduino-based flame detection system

An Arduino board can be used as the core component of an IoT-enabled flame detection system. The Arduino can be used to read sensor data from a flame sensor and send that data to a cloud-based platform or a remote server using a communication module such as an ESP8266 .

To create an Arduino-based flame detection system, you will need to:

  1. Connect a flame sensor to the Arduino.
  2. Write a sketch using the Arduino IDE to read the sensor data and send it to the cloud or remote server.
  3. Connect the communication module to the Arduino and configure it to connect to a Wi-Fi network.
  4. Upload the sketch to the Arduino.

Once the system is set up and connected to the internet, it can send sensor data to a cloud-based platform, such as ThingSpeak, where the data can be visualized and analyzed.

Additionally, you can set up notifications or alerts to be sent to a phone, email or any other device when a flame is detected, this can be done by using webhooks, IFTTT or other similar services.

Purpose of this project :

In this project we will realize an intelligent fire detection system with the Arduino board connected to the Internet.

It mainly uses a KY-026 flame sensor.

When the flame sensor detects a flame, the Arduino board sends an alert email by WIFI.

Necessary components

Arduino UNO

The Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins, 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. The Arduino UNO is programmed using the Arduino software (IDE), which is available for Windows, Mac, and Linux. The board can be powered by an external power supply or by USB. It is compatible with a wide range of sensors, actuators, and other devices, which can be connected to it using a variety of communication protocols, such as I2C, SPI, and UART. The Arduino UNO is a popular choice for beginners and hobbyists, as it is easy to use and has a large community of users and developers

KY-026 flame sensor

The KY-026 flame sensor is a type of flame sensor that can be used with an Arduino board to detect the presence of a flame. It is a simple and inexpensive sensor that consists of a photodiode, which detects the infrared radiation emitted by a flame, and a comparator circuit, which compares the infrared radiation level to a reference level and outputs a digital signal.

ESP8266 wifi

An ESP8266 WiFi module can be used in combination with an Arduino board to add wireless connectivity to an Arduino project. The ESP8266 is a low-cost Wi-Fi module that can be easily integrated with an Arduino board using the Arduino IDE. It allows the Arduino to connect to a Wi-Fi network and send or receive data over the internet.

To use an ESP8266 module with an Arduino, you will need to connect the ESP8266 to the Arduino’s serial pins (RX, TX) and power pins (VCC, GND). Then, you can use the Arduino IDE to upload a sketch to the Arduino that will configure the ESP8266 to connect to a Wi-Fi network and send or receive data using the Wi-Fi connection.

Connecting wires

When connecting wires to an Arduino or other electronic devices, it’s important to ensure that the wires are connected to the correct pins and in the correct orientation. Typically, the wires are connected to the power, ground, and input/output (I/O) pins on the device. The power and ground pins provide a source of power for the device, while the I/O pins are used to send and receive data.

Test plate

A test plate is used to include the flame sensor module, as well as connectors and other components to interface the sensor with the Arduino. It may also include LEDs, buttons or other input/output devices to test the functionality of the sensor and the microcontroller. The test plate allows for easy testing and validation of the sensor and the Arduino code that is used to interact with it.

To perform the assembly, you can connect:

KY-026 flame sensor:
