  Smart Air Quality Monitoring System using IoT

  By Vipra Bohara, Kaustubh Bajaj, Kinshuk Saini, Lakshay Kacholia, Mayank Sharma

  Abstract: This paper presents the design and implementation of a Smart Air Quality Monitoring System using the ESP32 Wi-Fi microcontroller integrated with an MQ-2 gas sensor and a DHT-11 temperature and humidity sensor. The system continuously monitors environmental parameters including air quality (smoke, LPG, CO, and other combustible gases), temperature, and relative humidity in real time. The acquired sensor data is transmitted wirelessly to the Blynk IoT platform, enabling users to …

  Automatic Gas Leakage Detection System

  By Mayank S. Kulkarni, Sudesh S. Godase, Pratik B. Godase, S.S. Gangonda

  Abstract: This project report presents the design and implementation of a focused automatic gas leakage detection and ventilation system centered on the Arduino Nano microcontroller and the MQ-2 gas sensor. The primary function of the system is to detect flammable gases like LPG, propane, and methane using the MQ-2 gas sensor. This sensor continuously monitors the surrounding air for the presence of these gases. When the gas concentration crosses a predefined …
