🔥 Sensor Hierarchy in Action! Testing 10 different Sensors with Raspberry Pi Pico | OOP MicroPython

In this **follow-up video**, we take our **sensor class hierarchy** to the next level by **demonstrating 10 different sensors**, including a **flame detection sensor**! This video showcases **digital, analog, and hybrid sensors** and highlights the power of **object-oriented programming (OOP) with polymorphism** in **MicroPython**.

By applying **OOP principles**, we show how **easily adaptable** a well-designed **class hierarchy** can be. In a **real-world demonstration**, we implement a **fire detection system** that triggers an alarm when a flame is detected. Then, with just **one line of code changed**, we swap in a different sensor—without modifying the system’s logic!
