SMART ALARM CLOCK / ESP32 APPLICATION
Smart Alarm Clock
基于 ESP32、OLED、DHT11、PIR、MAX98357A 和 Flutter 的局域网智能闹钟教学原型。
About this project
About this project
A teaching-grade LAN alarm clock: an OLED shows time and room conditions, a DHT11 reads temperature and humidity, a PIR watches for movement, a physical button silences the ring, and the sound comes from a MAX98357A playing PCM files stored in SPIFFS, with NTP keeping time. A Flutter app talks to it over plain HTTP REST to list, add, edit and delete alarms, read status and send a stop command; there is no authentication or TLS, and the notes restrict it to an isolated trusted LAN. No ringtone ships with the code because redistribution rights for the original WAVs could not be confirmed, so it still builds but stays silent.
