Introduction

Fire is an unpredictable disaster that can occur at any time, causing enormous losses. Therefore, it is essential to have a fire detection system that can provide warnings or notifications during a fire. This article will discuss the design of fire detectors that use the MQ-5 sensor to detect gas and smoke, as well as a photodiodic sensor to detect fire. This tool is also equipped with a report delivery function via mobile phone that will facilitate a quick response to the potential of fire.

Background and Importance of Fire Detection Systems

Fire detection systems are crucial in preventing and minimizing losses caused by fires. These systems can detect the presence of gas, smoke, or fire, and provide warnings or notifications to individuals or authorities. The importance of fire detection systems lies in their ability to:

Reduce losses: Fire detection systems can minimize losses experienced by individuals and companies by providing early warnings or notifications.
Improve safety: These systems can improve safety in various environments, such as homes, office buildings, factories, and public places.
Increase awareness: Fire detection systems can increase awareness and readiness to face unexpected fire disasters.

System Design

This fire detection system is designed using the ATmega8 microcontroller. The main components of this tool include:

MQ-5 Sensor

The MQ-5 sensor is able to detect the presence of gas, such as LPG and smoke. The MQ-5 sensor will issue analog signals related to gas content in the air. If the measured voltage on the sensor reaches ≥0.2 volts, this indicates the presence of gas, which will be followed by activation of buzzer and indicator lights to provide visual warnings and sounds.

Photodioda Sensor

The photodioda sensor serves to detect fire. When the photodioda detects the light produced by the fire, it will send a signal to the microcontroller to activate the buzzer and indicator lights, as well as make a call to the previously programmed cellphone.

GSM Wavecom Module

The GSM Wavecom module serves to send notifications via SMS or make phone calls when a fire or dangerous gas is detected. This module is very important because it provides a fast and effective way of communication, allows immediate responses from related parties.
