Description

Get hands-on with IoT as you build a complete weather logging system from scratch! This course focuses on integrating the ESP32 microcontroller, MicroPython programming, and MQTT protocols to create a versatile weather logger that gathers, logs, and transmits weather data seamlessly.

Designed for both IoT enthusiasts and intermediate-level developers, this course will walk you through the essential skills to transform a simple ESP32 module into a fully functional weather monitoring system. We’ll cover how to set up sensors, utilize MQTT for data transmission, and leverage MicroPython for efficient data handling. By the end of this course, you’ll be able to create your own connected weather logger, capable of sending data to cloud services or local networks.

In addition to practical projects, we’ll explore troubleshooting techniques, provide guidance on optimizing performance, and explain the best practices for managing MQTT messaging. With over 38 minutes of concise, targeted content, this course is perfect for learners who want to see real results quickly without overwhelming technical jargon.

Key Features:

  • Step-by-step guidance on setting up and coding with the ESP32 and MicroPython

  • Practical lessons on sensor integration and real-time data handling

  • Overview of MQTT basics and advanced usage for IoT communication

  • Customizable weather logger project that can be adapted for other applications
