From the project

IoT Air humidifier controller built around two microcontrollers: an STM32F446RE and an ESP32-S3

Projekt zakładał stworzenie sterownika nawilżacza powietrza opartego na dwóch mikrokontrolerach STM32F446RE oraz ESP32-S3. STM32 odpowiada za sterowanie wentylatorem sygnałem PWM, obsługę czujników oraz maszynę stanów, na której opiera się działanie systemu. ESP32 służy wyłącznie do połączenia urządzenia z Wi-Fi, a następnie chmurą AWS IoT Core (Amazon) poprzez protokół MQTT.
