Now that the basic agponic-MD unit is completed – I am working through all the different features that can be found on the unit and define there functions.

Here is one side of the connection box at the back of the unit.

A big part of the aquaponic simulator is the fact that it uses standard RJ-45 jacks to interface with Arduino’s or a Raspberry PI.  Having this type setup helps keep all the wires and connectors that are required for the unit to operate in a consistent manor safe and out of possible interaction with water elements.

Here is what is needed to construct this sub-assembly:

When all the above parts come together the finished product looks like this:

Here is what goes into the Tower Tubes and provides the water to the top and wiring for the sensor.  The sensor configuration is a “Water Sensor” and “Temp Prob” combination.  These have waterproof connectors that can be disconnected when the towers are removed to be taken to market or needing media to be pulled out once a crop is spent.

TOWER INTERFACE PLATE — protects the dry core of the tower base September 25, 2013

Here is the “INTERFACE PLATE” —  this plate is inserted into the base of the towers and is sealed.  With this interface plate in place wires can be run to tower sensors and power supplied to the pumps that feed the towers.  Without these interface plates it would be dangerous to provide power to pumps or connect or disconnect the tower columns.

Well thanks to Terry King and his comment – that he has DS18B20’s working fine with arduino IDE 1.0X.  I double downed my efforts to get 1.0.2 arduino IDE working.  I un-installed all versions – dumped all the libraries and started from a clean system again.  Loaded everything up and got all the new  libraries.  EVERYTHING WORKED FINE!  Thank you Terry!

What is an aquaponic device for IoT-aquaponics June 11, 2013

Aquaponic devices can come in many sizes and shapes.  There are simple and complex devices as with all technologies.

The most simple aquaponic device would be a temp probe connected up to an Arduino with the data generated being sent out to a Cloud service like Xively/Cosm/Pachube or ThingSpeak via ethernet or wireless connection.

I am working on a more complex aquaponic device right now that will contain the following sensor set:

pH sensor

3 – DS18B20 probes

1 – Flow meter

3 – media sensors

1 – Float Switch

1 – Humidity and Temp probe (DHT-22)

3 – gravity feed valves controlled by relays

1 – air pump controlled by relay (in N/O) configuration

1 – back-up air pump that turns on if electric goes out

1 – heater controlled by relays driven by temp reading being generated by the DS18B20 probes.

This device will be my proto-type to test sensor configurations and try new sensors out.  It will allow me to gain an understanding of how all this IoT technology comes together and can actually perform work with out me having to constantly watch my system.  I would like to be in Hawaii and just have my iPhone alert me when an event is out of range.  Then I could make the necessary adjustments over my Aquaponic API software and be done with it while at the beach.

I have resisted moving to Arduino IDE 1.0.x as I have read that people have had problems moving to it.

In my case I have been using ver 21 IDE because it was stable and all the libraries worked with it.  Now that I am moving to the IoT platform I am required to use Arduino IDE 1.0.x.

First step was to download and install.  Then needed to re-establish all the libraries required to work with DS18B20.  Once all done it was time to determine if it all would work correctly.

To start off I ran the one-wire finder sketch.  Much to my delight it worked.  Now I was very confident that this transition was going to go smoothly.   I now connected up 3 sensors and loaded my 3 sensor sketch.

Here was my result:

DS18B20 - 1.0.x

I got reading that were incorrect or really no readings at all

Next I had to make sure the hardware was connected right.  So I went back to my ver. 21 IDE and re-tested everything.  Sure enough everything worked great.

The results now is that using the Hacktronics sketch that was stated to be workable with Arduino IDE 1.0.x does not work with my set-up.  Now I will have to determine just what the problem is and how to correct it.

This will have to be my next task in learning about the DS18B20 and Arduino.

DS18B20 — new probe set established August 13, 2012

Next step in getting to determine if I can get 20 probes to configure correctly,  is to determine the HEX code for each probe.  Being that I had 10 left to pull of the HEX I got to work on this task.  Here are the results.

P022 — 0x28, 0x67, 0x22, 0x47, 0x03, 0x00, 0x00, 0xA1

P023 — 0x28, 0xAC, 0x30, 0x47, 0x03, 0x00, 0x00, 0x39

P024 — 0x28, 0x4A, 0x18, 0x47, 0x03, 0x00, 0x00, 0x64

P025 — 0x28, 0x1A, 0x3A, 0x47, 0x03, 0x00, 0x00, 0x31

P026 — 0x28, 0x66, 0xC1, 0x7A, 0x03, 0x00, 0x00, 0xD7

P027 — 0x28, 0xA2, 0x51, 0x47, 0x03, 0x00, 0x00, 0xF6

P028 — 0x28, 0xB5, 0x1F, 0x47, 0x03, 0x00, 0x00, 0x63

P029 — 0x28, 0x9B, 0xC0, 0x7A, 0x03, 0x00, 0x00, 0x22

P030 — 0x28, 0xBE, 0xB6, 0x7A, 0x03, 0x00, 0x00, 0x8E

P031 — 0x28, 0x20, 0x15, 0x47, 0x03, 0x00, 0x00, 0x84

Now I have the HEX code I need to enter all the information into my INDEX of probes so I can track each probe and where I have them located in my systems.  Helpful to know if I move them around in the future.  I had been using the procuct “MANYMOON” for tracking, but have since switched over to “EVERNOTE”.  This has proved to be a better platform for me as I can manage larger amount of information on a large amount of projects.  Evernote also allows me to have access to my information on any device I am using.  Great Stuff.

Here is what my index now looks like:

HARNESS TESTING — very important — DS18B20 April 20, 2012

use your multimeter

Now that I have constructed an addition harness I need to make sure it works.  Two (2) tests needs to be performed.  Conductivity and ohm confirmation of the resistor value through the connections.

CONDUCTIVITY:

This test will let me know that all my connections are correctly connected and signal is flowing through the wires and working the way I configured them.  If not,  I will need to correct the problem and retest until the connections are working correctly.

Here is a video of the testing I did:

http://youtu.be/0OZzv69DhF0

ohm Value Testing:

This is important with DS18B20 probes.  It is important because the DS18B20 IC’s  are sensitive when it comes to resistor values and there  tolerance levels.  I bought some very cheap 4.7K ohm resistors and did not know the tolerance level.  Hooked everything up and the probe did not work.  I had to trouble shoot all the connections and everything was working – then I swapped out a resistor that I knew worked and had specs on and bingo everything was working.  I have no problems using resistors with a 5% tolerance rating.  They will give you some swings in value readings, but the DS18B20’s will work very well it you stay in this tolerance range.

Here is a video of how I tested for ohm’s:

http://youtu.be/xhykQ61xfW0

Now on to building another harness and test it all
