The Integrated Air Quality and Hazardous Gas Detection System uses Internet of Things (IoT) technology to monitor air quality, temperature, humidity, and hazardous gases like CO₂ and NO₂ in real-time.
Integrated Air Quality and Hazardous Gas Detection System (IAQHGDS)
The Integrated Air Quality and Hazardous Gas Detection System leverages IoT technology to monitor air quality, temperature, humidity, and hazardous gases like CO₂, NO₂, and NH₃ in real-time. Designed for industrial and urban safety, it sends sensor data to the Blynk cloud platform, allowing remote monitoring, automated alerts, and historical analysis.
💡 Key Features
- 📡 Real-Time Monitoring: Tracks gas levels, temperature, and humidity.
- 🌐 IoT Integration: Uses ESP8266, DHT22, MQ135 sensors with Wi-Fi.
- 📲 Remote Visualization: Blynk app/web dashboard for live readings.
- 🚨 Safety Alerts: Trigger alarms or exhaust fans on unsafe gas levels.
- ☁️ Cloud Storage: Enables trend analysis and data-driven decisions.
🧩 System Components
- ESP8266 NodeMCU – Wi-Fi microcontroller
- MQ135 Gas Sensor – Detects CO₂, NH₃, benzene, and alcohol
