How to make an ESP32 Air Quality Monitor | Real-Time Gas, Temperature & Humidity | IoT project 🤯🤯

Описание: In this video, I built an ESP32 Air Quality Monitor that displays real-time air quality, temperature, and humidity data on a 1.3-inch OLED display.

This IoT-based project uses an ESP32 microcontroller, an MQ gas sensor, and a DHT11 sensor to monitor indoor air conditions. The data is processed by the ESP32 and displayed clearly on the OLED using the U8g2 graphics library.
This project is ideal for IoT beginners, engineering students, and DIY electronics enthusiasts.

The system can be used as a basic air quality and gas detection unit for homes, offices, and labs. It also serves as a great mini-project or learning project for understanding ESP32, sensors, and OLED displays.
