IoT-Enabled Air Quality Monitoring System Using Arduino

Introduction

The IoT-Enabled Air Quality Monitoring System is an advanced project designed to measure and analyze air pollution levels in real-time. Using Arduino and various environmental sensors, this system collects data on air quality parameters such as temperature, humidity, CO₂ levels, and particulate matter (PM). The collected data is then transmitted to an IoT platform for remote monitoring and analysis.

Key Features

• Real-Time Air Quality Monitoring: Detects pollutants such as CO₂, PM2.5, PM10, and harmful gases.
• Arduino-Based System: Uses sensors like MQ135, DHT11, and SDS011 for accurate readings.
• IoT Integration: Sends data to cloud platforms like ThingSpeak or Blynk for real-time tracking.
• User Alerts & Notifications: Provides alerts when pollution levels exceed safe limits.
• Portable & Low Power Consumption: Can be powered by batteries or solar panels for outdoor use.

How It Works

1. Sensors collect environmental data such as gas concentrations and air temperature.
2. Arduino processes the data and sends it to an IoT server via WiFi or GSM module.
3. Users can access air quality reports through a web dashboard or mobile app.
4. Alerts are triggered if pollution levels cross predefined thresholds.

Applications

• Smart Cities: Helps government authorities monitor air pollution levels.
• Industrial Safety: Ensures workplace air quality in factories and mines.
• Home & Office: Provides real-time indoor air quality monitoring for a healthier environment.

This IoT-enabled air quality monitoring system is an essential tool for promoting environmental awareness and ensuring better living conditions through data-driven insights.
