A Practical ESP32 Guide to Building the Smallest Useful Physical AI Loop: Sense One Thing, Act on It
blaizedsouza · x · 2026-09-06
The author demonstrates the smallest useful physical AI project with a demo box where a flame sensor triggers a water tube to extinguish the fire — the basic loop of physical world → sensor reading → decision → action.
Alongside it is a practical ESP32 article covering how to choose sensors (distance, motion, heat, sound, touch), wire them safely, filter noisy readings, and turn physical changes into reliable actions, plus a safe first project to start with.
