IoT Based GAS Leakage Detector and Alarming System

Introduction

In an age where safety and automation go hand in hand, the IoT Based GAS Leakage Detector and Alarming System stands out as a crucial project for ensuring safety in homes and industrial settings. This advanced system leverages the power of the ESP-32 microcontroller to detect gas leaks and take immediate action, making it an ideal project for final-year Electrical and Electronics Engineering (EEE) students.

Project Overview

This IoT-based gas leakage detection system is designed to sense the presence of hazardous gases, such as LPG or natural gas, and promptly respond by triggering alarms, turning off the gas supply, and notifying the user via email. The system integrates multiple components to ensure accurate detection and efficient response to gas leaks.

Components

1. ESP-32 Microcontroller: The core of the system, responsible for processing sensor data and controlling other components.
2. 5V 5A SMPS: Provides a stable power supply to the entire system.
3. Gas Sensor: Detects the presence of hazardous gases in the environment.
4. Servo Motor: Automatically turns off the gas valve to prevent further leakage.
5. 5V DC Fan: Helps to ventilate the area by dispersing the leaked gas.
6. Buzzer: Emits a loud sound to alert nearby individuals of the gas leak.
7. LCD Display with I2C: Displays real-time data and system status.
8. Blynk App with Email Notifications: Sends real-time alerts and notifications to the user’s smartphone and email.

Features and Benefits

Real-Time Gas Detection

The gas sensor is highly sensitive and capable of detecting even minute gas leaks. Once a leak is detected, the sensor sends data to the ESP-32 microcontroller, which processes the information and triggers appropriate responses.

Automatic Gas Valve Shutoff

The servo motor is programmed to turn off the gas valve immediately when a leak is detected. This automatic shutoff feature prevents the gas from leaking further, reducing the risk of fire or explosion.

Ventilation with DC Fan

The 5V DC fan is activated to ventilate the area by dispersing the leaked gas, ensuring that the environment remains safe and the concentration of the gas is reduced to non-hazardous levels.

Audible Alarm

The buzzer produces a loud alarm sound to alert anyone nearby of the gas leak, ensuring immediate attention and action.

Real-Time Monitoring and Notifications

The system is integrated with the Blynk app, allowing users to monitor the status of the system in real-time from their smartphones. Additionally, the system sends email notifications to inform users of any detected gas leaks, ensuring they are aware even if they are not at home.

LCD Display

The LCD display with I2C interface provides real-time data, including gas concentration levels and system status, making it easy to monitor the system locally.

How It Works

Step 1: Gas Detection

The gas sensor continuously monitors the environment for the presence of hazardous gases. When it detects gas above a certain threshold, it sends a signal to the ESP-32 microcontroller.

Step 2: Data Processing

The ESP-32 processes the sensor data and determines whether the gas concentration is dangerous. If the levels are above the safety threshold, the microcontroller activates the alarm system.

Step 3: Activation of Safety Measures

• Servo Motor: The ESP-32 sends a signal to the servo motor to turn off the gas valve, stopping the gas supply.
• 5V DC Fan: The fan is activated to help ventilate the area.
• Buzzer: The buzzer is triggered to alert nearby individuals of the gas leak.

Step 4: Notifications

The ESP-32 sends real-time data to the Blynk app, which notifies the user on their smartphone and via email about the gas leak, providing information on the gas concentration and system status.

Project Implementation

Hardware Setup

1. ESP-32 Microcontroller: Connect the gas sensor, servo motor, DC fan, buzzer, and LCD display to the ESP-32.
2. Power Supply: Ensure a stable power supply using the 5V 5A SMPS.
3. Gas Sensor: Position the sensor in a place where gas leaks are most likely to occur.
4. Servo Motor: Attach the motor to the gas valve for automatic shutoff.
5. DC Fan and Buzzer: Place them in positions where they can effectively disperse gas and alert individuals.

Software Development

1. Arduino IDE: Use the Arduino IDE to program the ESP-32.
2. Blynk App Integration: Configure the Blynk app to receive real-time data and notifications.
3. LCD Display: Program the I2C interface for the LCD to display real-time data.
