Introduction

Fire Detection and Alarm System for Home and Industrial Safety is an innovative project designed to detect potential fire hazards and alert users in real-time. Utilizing an Arduino UNO microcontroller, sensors, and a relay module, this system monitors environmental conditions like temperature, smoke, and flame, ensuring a reliable early-warning mechanism against fires. This project is ideal for EEE final-year students, providing hands-on experience with IoT and sensor integration for a life-saving application.

Project Overview

This fire detection and alarm system detects fires based on multiple parameters, including temperature, smoke, and flame presence. By connecting various sensors (such as the flame sensor, gas sensor, and DHT-11 for temperature) to an Arduino UNO, the system constantly monitors the surroundings. If a potential fire hazard is detected, the system activates an alarm via a buzzer and displays real-time data on an LCD screen. It can also trigger additional safety devices like exhaust fans through a relay module.

Components Used

Here’s a list of the primary components for the Fire Detection and Alarm System for Home and Industrial Safety:

• Arduino UNO: Central microcontroller to process data from sensors.
• DHT-11 Sensor: Measures temperature and humidity.
• Gas Sensor (MQ2): Detects smoke and other gases in the air.
• Flame Sensor: Senses flame presence to identify fire threats.
• Current Sensor: Monitors electrical current levels.
• 1 Channel Relay Module: Controls external devices like fans.
• Buzzer: Emits sound as an alert.
• LCD Display: Displays real-time data from sensors.
• SMPS (Switch Mode Power Supply): Provides a stable power source.
• Fan: Operates as an exhaust to clear smoke.

Optional Components:

• Wi-Fi Module: For remote monitoring and notifications.

Each component plays a crucial role in detecting and responding to fire hazards, making the system versatile for both home and industrial use.

Circuit Diagram and Working Principle

The circuit diagram for this Fire Detection and Alarm System for Home and Industrial Safety shows the connections between the Arduino UNO and the various sensors and output devices. The Arduino acts as the brain of the system, processing data from sensors and controlling the output.

• Temperature and Gas Monitoring: The DHT-11 and gas sensor continuously send data to the Arduino. If temperatures rise above a certain threshold or if smoke is detected, the system is triggered.
• Flame Detection: The flame sensor identifies the presence of flames and sends a signal to the Arduino.
• Alarm Activation: If any sensor detects a fire hazard, the Arduino activates the buzzer for an audible alert and displays a warning message on the LCD screen.
• Fan Control: The relay module activates a fan to dissipate smoke, controlled by the Arduino.

Step-by-Step Guide

1. Setting Up Components: Connect each sensor to the Arduino UNO based on the circuit diagram. Ensure connections are secure for accurate readings.
2. Programming the Arduino: Use Arduino IDE to upload code that reads sensor data, analyzes it, and controls outputs like the buzzer and relay module.
3. Testing: Test each sensor individually to ensure they respond to temperature, smoke, or flame conditions.
4. Calibrating Thresholds: Adjust thresholds for temperature and smoke detection based on specific needs.
5. Final Assembly: Mount all components in an enclosure for safe operation.
