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.

DS18B20 – always a new twist June 10, 2013

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:
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.

I am getting closer to getting 20 probes ready to test. Everything is just about in place to make a run at it. So stay tuned we are getting close now…….
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:

The next step to achieving running 20 probes was to complete the 4.7K resistor harness set-up. I now have this done and can move on to the finishing off the ground connector that will allow pull all this together.
HARNESS TESTING — very important — DS18B20 April 20, 2012

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:
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:
Now on to building another harness and test it all

Once I got the ground problem worked out and was reading one probe adding 4 more was no sweat…….
Here is the sketch I used: ( you will need to change out the HEX code parts for your specific DS18B20)
// This Arduino sketch reads DS18B20 “1-Wire” digital
// temperature sensors.
// Tutorial:
// http://www.hacktronics.com/Tutorials/arduino-1-wire-tutorial.html
//Changed sketch to handle individual temperature probes for testing out software and hub
//each probe is plugged into a wiring harness using either a 4.7K or 2.2K resistor configuration.
//will use this to test power soruce and resistor needed to read 5 temp probes.
