Tutorial 11 | Raspberry Pi Pico | MicroPython | Improved Weather Station with DHT11 and inheritance
In this 11th episode of the *Object-Oriented Programming with MicroPython on Raspberry Pi Pico* tutorial series, we demonstrate the real power of OOP by using *inheritance* to expand our **weather station project**. 🌦️🌡️
We introduce a *DHT11 temperature & humidity sensor* to measure *indoor weather conditions* and extend our WeatherStation project—all **without changing any of our existing code**. By leveraging **inheritance and subclasses**, we seamlessly add new features while keeping our design clean and modular.
In this tutorial, you’ll learn:
How *inheritance* helps extend classes without rewriting existing code.
How to create a subclass to add *indoor temperature and humidity* to the WeatherStation.
How to update and reuse our existing *object model* with new functionality.
How to run the project in both the *Wokwi simulator* and on *real hardware* with a DHT11 sensor.
This episode highlights the elegance of OOP design and shows how *modularity, reusability, and scalability* come together in MicroPython projects.
