Project Overview – Air Quality Monitoring Station Series, Part 2

Lesson Objective
In this lesson, you will get a clear overview of the IoT Air Quality Monitoring Station you will build.
By the end of this lesson, you will understand the purpose of the project, how it works, and its key components.

List of required components:

	AHT10 high-precision temperature and humidity sensor
	TTGO T-Display ESP32 16MB with WiFi, Bluetooth and 1.1" colour LCD screen
	Dupont cables, 40 pcs

Project Purpose
The IoT Air Quality Monitoring Station is designed to measure temperature and humidity and display this data both on a screen and on a web page on the local network; remote access requires a separately secured setup. The project demonstrates the practical use of IoT technology in environmental monitoring, an important part of smart homes, agriculture and industrial applications.

Core System Features

1. Data Collection: The AHT10 sensor collects temperature and humidity data.
2. Data Display: The TFT screen displays real-time readings.
3. WiFi Connection: ESP32 connects to a WiFi network and acts as a web server.
4. Remote Monitoring: ESP32 hosts a simple web page that lets you view sensor data remotely.

How It Works

• Sensor Data: The AHT10 sensor collects temperature and humidity data, which is processed by ESP32.
• Data Output: The processed data is displayed on the TFT screen and accessed as a web page through ESP32's WiFi connection.

Applications
This project simulates real-world IoT applications such as smart home monitoring, environmental control in agriculture and industrial safety systems.

Key Learning Points

• You will build a system that monitors environmental data and displays it both locally and over WiFi.
• The project integrates sensor data collection, real-time display and web-based access—fundamental principles of IoT.

In the next lesson, you will prepare your development environment and tools to start building this project!
