From the project

Complete firmware and hardware solution for a self-watering pot, written in C++

Projekt zakładał stworzenie automatycznej, samopodlewającej się doniczki na mikrokontrolerze STM32F446RE. Firmware jest napisany w C++. System pilnuje wilgotności gleby i sam włącza pompkę, kiedy gleba robi się za sucha. Da się też wymusić podlewanie ręcznie, a system ma kilka zabezpieczeń na wypadek, gdyby coś poszło nie tak (zaklinowana pompa, uszkodzony czujnik, zawieszony program, pusty pojemnik na wodę).
