Practical ESP32 sensor guide: build reliable perception loops for physical AI before adding LLMs
TinfoilTricorn · x · 2026-09-17
Using a handmade VAS DMSR human-tracking radar prototype, the author argues a robot must first make one signal reliable before it can understand a room: a handheld unit turns the space ahead into a live sector view with angle, average distance, and differential readouts. The core loop for physical AI: physical world → sensor reading → filtering → decision → action. The accompanying ESP32 guide covers distance, motion, heat, sound, and touch sensing — choosing sensors, safe wiring, and filtering noisy readings before they trigger actions.
