Introduction
The Automated Air Pollution Monitoring System using Arduino UNO is a practical project for school and EEE final year students. This system provides real-time monitoring of air quality by detecting harmful gases and temperature levels using sensors like MQ-2, MQ-6, and LM35. The measured data is displayed on an LCD with I2C, making it a useful tool for understanding pollution levels in any environment. This project is designed to offer hands-on experience in electronics, coding, and environmental monitoring.
Project Overview
The primary objective of this project is to create an automated system that continuously tracks air quality and alerts users when pollution levels exceed safe limits. The system is powered by a 5V 5A SMPS and uses an Arduino UNO as the main microcontroller. Key features include:
- Real-time temperature and gas monitoring.
- Alerts through a buzzer and a light.
- Display of results on an LCD with I2C.
This project not only serves as an educational tool but also raises awareness about the importance of air quality monitoring.
Components Required
- Arduino UNO: The main microcontroller that controls the entire system.
- 5V 5A SMPS: Power supply for the system.
- LM35 Sensor: Measures temperature.
- MQ-2 and MQ-6 Sensors: Detect harmful gases like carbon monoxide and smoke.
- Buzzer: Provides audio alerts when pollution exceeds safe levels.
- 1-Channel Relay: Controls the light to indicate high pollution levels.
- Light: Visual alert for high pollution levels.
- LCD with I2C: Displays temperature and gas levels.
How the Automated Air Pollution Monitoring System Works
The Automated Air Pollution Monitoring System operates by continuously sensing the environment using MQ-2 and MQ-6 gas sensors along with the LM35 temperature sensor. The Arduino UNO processes this data and triggers alerts through the buzzer and light when pollution exceeds predefined thresholds. The system’s output is displayed on an LCD with I2C, providing clear and real-time readings.
Key Features:
- Real-time Monitoring: The system continuously checks the air quality and temperature, offering up-to-date information.
- Automatic Alerts: If the detected gas levels or temperature exceed the set limits, the system activates the buzzer and lights up the alert light.
- User-friendly Interface: The data is displayed on an LCD, making it easy for users to monitor.
Step-by-Step Guide
- Component Assembly: Connect the sensors (LM35, MQ-2, and MQ-6) to the Arduino UNO. Attach the LCD with I2C for displaying data. Wire the relay, buzzer, and light as per the circuit diagram.
- Coding: Write and upload the code to the Arduino UNO using the Arduino IDE. The code will read data from the sensors and trigger alerts based on preset thresholds.
- Testing: Once the system is powered, verify that the sensors are reading accurate data and the alerts function properly when pollution levels rise.
- Calibration: Adjust the thresholds in the code based on real-world conditions to ensure accurate monitoring.
Applications of the Project
This Automated Air Pollution Monitoring System has diverse applications:
- Educational Tool: Ideal for school projects and EEE final year students to learn about environmental monitoring and automation.
- Home and Office Monitoring: Useful for checking indoor air quality to ensure a healthy living or working environment.
- Public Awareness: The system can be installed in public areas to display pollution levels, promoting environmental consciousness.
Conclusion
The Automated Air Pollution Monitoring System using Arduino UNO is an innovative project that addresses a critical environmental issue. By monitoring air quality and providing real-time alerts, this project empowers users to take timely action against pollution. With its simple design and practical applications, this project is both educational and impactful, making it a perfect choice for school and EEE final year projects.
