🌍 Smart Pollution Alert System using ESP8266 and MQ135 Gas Sensor 🌫️

In this project, we’ll build a Smart Air Pollution Monitoring and Alert System using an ESP8266 (NodeMCU) and an MQ135 Gas Sensor. This system continuously monitors air quality and sends alerts when pollution levels rise beyond a safe limit. The data can also be viewed in real time via Wi-Fi on your smartphone or web dashboard!

✨ What You’ll Learn:

How to interface the MQ135 Gas Sensor with ESP8266

How to measure air quality (CO₂, NH₃, Benzene, etc.)

How to send real-time pollution data to a web server or cloud (like ThingSpeak or Blynk)

How to create a simple IoT-based environmental monitoring system

🧠 Components Used:

ESP8266 NodeMCU

MQ135 Air Quality Sensor

Jumper Wires

Breadboard

USB Cable & Power Supply

💡 Features:

Real-time air quality monitoring

Wi-Fi-based data logging

Automatic pollution alert notifications

Compact, low-cost IoT solution

📚 Code & Circuit Diagram:


📺 Watch till the end to see how the system detects pollution levels and sends smart alerts!
