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!
