Hello everyone, as I stated on the introduction page many months ago I have been building an aquaponics system with a team of fellow electrical and computer science engineers. The original goal of this project was to create a system that could be controlled and monitored via internet or smartphone app. So because of the control we needed a lot of electronic parts vs the mechanical ones most of you use.



So getting to it let me explain what we got.

Approximately 300 gal fish tank


(2) 4’ by 3’ Grow Beds


I used a little trap because I was fearful of getting a small stone in the electronic drain valve.


To control the water flow I have a small 12V DC sump pump with the fill and drain all controlled with electric ball valves. Water level is monitored by a electro-mechanical float switch.
All this is controlled with a Arduino, relays and H-bridges.


Due to time constraints we had to abandon the phone app and couldn’t get it attached to the internet so we fell on using a touch screen LCD.




Over the next few days I'll go into the problems that I ran into and some of them that I solved and some that are still problematic.
