Abstract

The IoT-Based Air and Gas Quality Monitoring System uses an ESP32 microcontroller integrated with DHT11, MQ2, and MQ135 sensors to monitor temperature, humidity, and harmful gases in real time. It detects pollutants such as carbon monoxide, methane, ammonia, and smoke to assess air quality levels. The system displays data on an I2C 16×2 LCD for immediate monitoring. It also sends SMS alerts via a GSM module when gas levels exceed safe limits. Using Wi-Fi, it connects to cloud platforms like ThingSpeak or Blynk for remote access and data visualization, making it an efficient and cost-effective safety solution.
