Story

Due to a lack of space, hydroponic cultivation is attractive for novice and experienced home gardens. This project aims to build an adapted interface HMI to control electronic hydroponic machine devices. The HMI aims to help keep the desired culture microclimate for indoor cultivation. The HMI is also used to keep track of the farmer's intelligence and experience.

The machine

Our machine is built to ensure plant feeding through water circulation. The first prototype is shown below :

The Hydroponique machine structure

The HMI

Hydroponic machines are water-based, Because of this, we have chosen an inductive sensing solution to build the HMI. The main implemented functionalities are:

starting or stopping the water pump,
flow control,
Water level,

We are using gloves on which we have glued aluminum foil.
