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.

Purpose of this project:

The flame detection system can use a Microbit microcontroller and an ESP8266 WiFi module to detect the presence of flame or fire. The Microbit is used to read data from the flame sensor and process the information, while the ESP8266 is used to connect the system to a WiFi network and transmit data to a remote server or other device.

In this project we will realize an intelligent fire detection system with the Micro: bit card connected to the Internet.

It mainly uses a KY-026 flame sensor.

When the flame sensor detects a flame, the Micro: bit card sends an alert email via WIFI.

Note: To connect the Micro: bit card to the Internet you can see this article:

KY-026 flame sensor

The KY-026 flame sensor is a type of sensor that is used to detect the presence of flame or fire. It typically consists of a sensor module that includes a photodiode and a comparator circuit. The sensor uses the photodiode to detect infrared radiation emitted by the flame, and the comparator circuit to compare the detected level of infrared radiation with a reference value. If the detected level exceeds the reference value, the sensor will output a signal indicating that a flame has been detected.

The KY-026 flame sensor can be used in a variety of applications, such as fire alarms, home security systems, industrial monitoring, and flame detection in vehicles. It can be interfaced with a microcontroller or other electronic device to trigger an action or send an alert when a flame is detected.
