If you love electronics as well as plants, what better way to combine the two than with a smart hydroponic system? Students at the Juan de Lanuza School decided to do just that, creating a portable hydroponic assembly that’s automatically controlled with the help of an Arduino Mega.
The system uses six lengths of PVC pipe to house plants and pass a nutrient rich liquid solution through their roots. The control assembly measures elements such as temperature, humidity, and pH, then adjusts the lighting, water pump, and nutrient feeder to accommodate for conditions.
The device transmits data to ThinkSpeak for human monitoring, and also features a smartphone app for visualization. Build details are available here in English, or you can see a video of the setup in Spanish below.
