Система полива растений на основе Arduino своими руками

Система полива цветов и других растений позволяет автоматизировать процесс ухаживания за флорой как в домашних условиях, так и в условиях огородных и садовых участков. Благодаря такой системе может быть получен более качественный урожай и продлена жизнь растений за счет их своевременного полива.

Для тех, кто не профессионал в электронике и не хочет покупать дорогостоящее оборудование для полива растений, предлагается сделать такую систему самостоятельно с помощью платы Arduino.

Данный проект основан на Arduino-подобной плате под названием Bluno компании DFRobot. Она имеет возможности беспроводного подключения по Bluetooth, поэтому при желании Вы можете контролировать полив растений с помощью мобильного телефона с поддержкой Bluetooth. Для измерения количества влаги в почве используется трехпроводной датчик влажности. Также для активации насоса, который будет обеспечивать подачу воды растениям, следует подключить модуль реле на 5 В. Помимо этого для отображения информации здесь применяется модуль OLED дисплея 2.7» 128x64. Схема подключения электрической части системы полива растений на основе Arduino представлена ниже.

Значение H, отображаемое на OLED-дисплее, определяет количество влажности, обнаруженную датчиком в почве. Растение находится в нормальном состоянии, если значение H составляет от 300 до 800; растение испытывает недостаток воды, если значение H меньше 300. Датчик почвы измеряет и выдает результат в абсолютных единицах (от 0 до 800), а влажность, отображаемая в Bluno, выражается процентах, поэтому итоговая влажность равна ((влажность почвы) / 800 * 100%).

Ниже приведен код программы для работы системы автоматического полива растений на основе Arduino.
