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
- Data Collection: The AHT10 sensor collects temperature and humidity data.
- Data Display: The TFT screen displays real-time readings.
- WiFi Connection: ESP32 connects to a WiFi network and acts as a web server.
- 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!
