ESP32-P4 Reads Water Meter with AI

This project builds on an earlier proof of concept where a 5-digit recognition system ran on the ESP32-S3. The new work steps up to a practical utility application, directly reading a water meter's pointer and digits. Using the Makerfabs ESP32-P4 board with autofocus, the developer gathered new images from an actual meter and trained a dedicated model. The successful recognition of the reading demonstrates that such tasks are possible on embedded hardware without cloud processing. While the results are promising, the article does not detail accuracy metrics or performance under varied conditions, so the robustness of the system remains untested. For business readers, this hints at the potential for low-cost, on-device AI in industrial and utility settings, though broader deployment would require further validation.
