The future of aquaponis has arrived and it is call IoT —  Internet of Things. or IoT-aquaponics.

Why do I think this, well view this data:


Here is a good YouTube on how this has developed over the past five years or so. (click on picture)

It became clear to me that the path I was on was leading me to a deadend when it comes to using a large number of DS18B20 probes.  The sketches I was working with had problems for me.  A number of comments and suggestions from readers along with research on my part I have figured out that the use of HEX code is the way to go. This new direction will get me to the end now.  This seems to be the most traveled path when it comes to the DS18B20 platform.  The best work I can find going this direction comes from two main sites. The first site Hacktronics.com has some very good tutorials on this subject.  The second site is a spin off of the Hacktronics site in that the same code is used, but changed to be output to a LCD display (very useful stuff).  These two sites will be very useful for me going forward and will enable me to finish-up on the Temp probe side of things and will allow me to move on to the others sensors I have been working with.

The first is:

Since I have been on my aquaponic automation quest I have been looking for all the components to make a aquaponic control unit.  Today catching up on my BLOG reading I ran across the last senor I needed to finish the feature set.  It is the DO (dissolved oxygen) sensor.  It is a nice to have functionality and one of the core measurements I want on my dashboard to monitor my aquaponic units.  Finding the sensor in one thing, but to find it and have a reference as to how to connect it up with an arduino is golden.    Now I will have to research out where to buy the sensor and find the time to test it and play with getting it to work.  When I know all there is about the sensor and the code needed to get working, I can then incorporate it into a working controller unit.  Here is the blog reference to the DO sensor.

Dissolved Oxygen Sensor

from Arduino Your Environment by Steve Spence

Looking for a way to detect dissolved oxygen levels? If you raise fish, this and a ph sensor are two important things to monitor (and of course, temperature), and an Arduino is the ideal platform to build upon. The Sensorex DO1200 ($139) outputs a <1mv – 54 mv signal indicating DO levels. Use
analogReference(INTERNAL1V1) to set the top of the input range to 1.1v.

Connect it to one of your analog pins. Very simple to read, just like a potentiometer.Subscribe to Green Trust Sustainability & Renewable Energy by Email
