myRIO Aquaponics

[SunainaK]

Overview of what project is:

Aquaponics is a sustainable farming method that combines the techniques of hydroponics (cultivating plants in water)   and aquaculture (raising aquatic animals in tanks) in a symbiotic environment. In an aquaponic system the waste produced by the fish provides the plants the nutrients they need to survive and grow.  Ultimately, aquaponics is a food production system that provides you with pesticide free fruits and vegetables, as well as delicious, high protein fresh water fish. In addition, aquaponics system uses 10% of water used in traditional farming, has small footprint and is ideal for gardening in an urban setting.

In this project, you will learn how to build a small aquaponic system and automate it with myRIO.  You will learn about flow meters, pH, ultrasonic and digital temperature sensors, as well as principles of signal conditioning and closed loop control.

Hi,

I am going to use the D18B20 temperature sensor for a different project, and would like to reuse the VIs in this project to interface with the temperature sensors. Is the VI configured to handle multiple temperature sensors on the same wire?

[MikhailK]

From what I recall, the code was written for one sensor. Also there's a utility for 1-wire devices on LabVIEW tools network:

Mikhail,

Thank you very much for your response. I will most certainly have a look at the example for the cRIO.

Hi,it looks great, i am working in something similar, have you tried with amonia and nitrate testers?.

[MikhailK]

Hi evilzone! I haven't tried those primarily because I wanted to keep the cost of system down. Those would certainly be great additions, especially for balancing the system (optimal ratio of fish to plants).

A big thanks for this great project !

Can I know, how to save the data obtained from the sensors. For example, the data obtained from the temperature sensor for every 1 hour .

Thanks for the project. But the project, can it work without the hardware connection? This is what seems on my version of LabView 2021. The booleans aren't working for me and the debug area shows NaN. How can it be fixed? Reply to me ASAP, please!!!
