Intelligent Smoke Detection System and Adaptive AI Threshold Optimization on an RA MCU Embedded Platform

Qiushi Xie^‡, Yutong Bai, Jinghuan Xiao, Yujiang Zeng^*

Apr–Aug 2025 · 8th National College Student Embedded Chip and System Design Contest — Chip Application Track · National Finals Second Prize

A lightweight smoke time-series prediction network deployed on the Renesas RA6M5, demonstrated through a dual-board comparison between AI prediction and a fixed-threshold baseline. It provides warnings 3–5 seconds earlier with a false-alarm rate below 0.5%, using a low-cost optical dust sensor and fully local MCU inference for affordable, offline operation.
