ESP32 Weather Station with Blynk & MQTT | MicroPython IoT Project + GitHub Code

🌦️ Build Your Own IoT Weather Station Using ESP32 + MicroPython!

In this video, I show you how to create a real-time weather station using an ESP32, the AHT20 sensor, and MicroPython. You'll see the full step-by-step coding process, sensor testing, and real-time monitoring in the terminal.

Although this video focuses on the core coding and hardware setup, the project also supports:

✅ MQTT — to publish sensor data to a local broker (like Mosquitto)
✅ Blynk IoT — to display live temperature and humidity on your phone (V3 = Temp, V4 = Humidity)

Both integrations are working and included in the GitHub repo linked below 👇

🔧 Project Requirements:

ESP32 board

AHT20 sensor

MicroPython firmware

MQTT broker (e.g., Mosquitto)

Blynk IoT app (cloud/mobile)

📂 GitHub Repository

💡 Whether you're monitoring your room, a greenhouse, or building a smart weather display — this beginner-friendly project is a great way to start with ESP32 and IoT!
