sascha-kirch/aquapi

AquaPi is a plant watering project using a Raspberry Pi and an Arduino Uno. The Raspberry Pi is the master device. It processes the user's input via a XBox controller, it shows a menu on the LCD display, it manages the Arduino and its connected sensors and it hosts and updates a database and a web interface. The arduino controlls the sensors and the actuators and communicates via USB with the RaspberryPi

Hardware

Electronics

The schemetic of the electronics is shown in the image bellow:

The table below shows an image of the components used for this project.

Component	Details	Image Model
Temperature and Humidity Sensor	DHT11, 16bit
Water level sensor	Capacitive sensor

Software

Database and Webinterface

A database is used to store information gathered by the sensors, to register one or more AquaPi setups and to store when the plant was watered. The following tools are used:

Component	Used Tool / Package	Installation commadn
Webserver	Apache2	sudo apt install apache2 -y
PHP	php 7.3	sudo apt install php7.3 php7.3-mbstring php7.3-mysql php7.3-curl php7.3-gd php7.3-zip -y
Database	MariaDB 10	sudo apt-get install mariadb-client mariadb-server
Database Management	PHPMyAdmin	sudo apt-get install phpmyadmin

A webinterface is provided, to retrive the content of the database and to provide help. The design is responsive and can be used on the smartphone as well (only workes on Android, due to the API used for graphical representation)
