🌦️ ESP32 Weather Station | Full System Explained (with Code + Live Demo)

In this video, I’ll walk you step-by-step through building a complete IoT Weather Station using the ESP32 — from reading real DHT11 sensor data to serving it over Wi-Fi via a web interface and UART commands!

🚀 What You’ll Learn:

How to interface a DHT11 temperature and humidity sensor with ESP32 using bit-banging.

How to save and load the last sensor readings using NVS storage.

How to send and receive UART commands (like “GET TEMP”).

How to create a web server that shows live sensor data in a clean HTML page.

How to build a /api JSON endpoint for integration with other apps or dashboards.

How to make the ESP32 try to connect to your home Wi-Fi first (STA mode) and automatically fall back to Access Point (AP mode) if connection fails.

How to handle Wi-Fi events, IP logs, and network setup properly to avoid errors like ESP_ERR_WIFI_MODE.

💡 Highlights:

Fully commented code with detailed English explanations for each part.

Works completely standalone — no cloud needed!

Built for ESP32--WROVER-I, but easily adaptable to other ESP32 boards.

Includes HTTP UI + JSON API + UART communication in one firmware.

📁 Code and Resources:
The full source code is shown in the video and available in the description below.

📸 Demo:
Watch the ESP32 connect, serve live weather data on a browser, and respond instantly to UART commands!
