Smart Hydroponic System

Prototype Concept

The idea is design an indoor smart hydroponic system which we can measure the environmental changes with sensors using Infineon products.

Element 14 Design Challenge – Sustain the World

Here is a block diagram of the concept design.


The idea is to create a photosynthesis inside garage and optimize the plant growth.


I’ve got the 2nd prize (runner up) in 2020 Element 14 Sustain the World Challenge contest

I built a proof-of-concept system in my garage.


I compared this PoC system with a commercial hydroponic system. Even though this system looks more like DIY work, we can monitor environmental changes over time and add extra control like wind and oxygen to the hydroponic system!

Here is the summary of the feature sets
