Backyard Aquaponics
A place to discuss aquaponics

Chiumanfu,

I'm truly amazed at your work. I"m setting up a small system and would like automate as much possible. As my system is small, I'll probably leave out the PH and DO sensors initially, but I would like to mirror you system as much as possible.

I see your link to GitHub, so thanks for that. I was wondering if I could purchase 3 sets of your PCB boards. I'm in the US. Thanks again!!

Chiumanfu,

Can I see right, the 5 DS18B20 temperature sensors are connected together!

Why? does it not effect the readings? since you are getting the readings from different locations in the system!

Thanks

What a great project. I'm setting up my first system (ibc tote) here in DC and wanted to make a sensor package that updated to my network. At this point I plan on using an Arduino Uno as I don't need to control/monitor nearly as many things are you are. it's mighty excellent of you to share as well. I do thank you.

The DS18B20 sensors are addressed using 1Wire. The arduino sends a data request to a specific address and that one sensor responds. This allows them all to be on the same data bus.

The caveat is that you have to discover the address of your particular sensors and edit those addresses into the firmware. It's not a difficult process and well documented in the source code.

In actual practice, all the growbed temp sensors and sump temp sensor always read the exact same. For my particular system, this season, I will probably just reduce it to one tank temp sensor and one growbed temp sensor.

Thanks Chiumanfu, I figured the DS18B20 out, it took a bit of trial and error.

Now I am on to grovestream, I will try and wrap my head around that one.

Can you tell us a bit more about the RJ11's?

How did you go about it, are they waterproof?

Can you maybe upload some detailed photos, especially the inside and such?

Thanks again.

The ones I bought are here, but it seems no longer available. They are very common so it shouldn't be hard to find a replacement.

They are not water proof so only use in a greenhouse or under shelter. They use screw down terminals so it's really easy to terminate and remove sensors if you have a failure. I used a tie wrap on the sensor cable as a strain relief which worked really well.

Chiumanfu, that looks amazing.

It got me thinking that I might get some RJ12's and put both the VIB Switch and the Temp Probe in one. What do you think?

I have tried to find the pH rev4.0 and theDO rev6.0 without any luck. (maybe someone knows???)

Would it be complicated to update the code for the EZO boards? or is it something more complicated?

Atlas offered to help me with it.

P.S. I asked Atlas about the rumoured ammonia, nitrate and nitrite sensors. They responded "They are garbage, they do not work. Stay away from those probes.".

RJ12 has 6 conductors so combining sensors would work fine.

The conversion to EZO syntax should be very simple. I haven't really looked into it but I could if you run into problems. If Altas converts the code for you, please post it up so I can merge it into the Github. I'm sure others are interested too.

Hello Chiumanfu

Can you give me an update on the 'new' pcbs you had mentioned you would be able sell once you had the tested finished? Have you checked them yet? I am really interested in starting the electronics side of the project now it is springtime here. Send me a PM if you want, I live in the mountains and only check my email, internet when I come to town each week.

Thanks

Sorry for the procrastination everybody. Lots of stuff happening in life. I'll work on it this weekend. I promise.

Thanks Chiumanfu

I'll be ready when you are, just let me know.....
Have a great weekend.

take care, peace

Hello Chiumanfu

I bought all the parts as they are listed in your 1st post of this topic more than a month ago. I am interested to buy the pcb of this project do you have any available?

Welcome to the forum Icaros

Hi All

First thing, a huge thank you to Chiumanfu for what he has created. Very impressed here.

Second, Just wanted to add myself to the list of enthusiasts who are very interested in the PCB boards.

Am in the planning stage for building our first aquaponic system which will be a chomp 2 system with 2 fish tanks, sump, filter, growth beds and a green house.
Biggest issue right now, is how to keep the water cool enough to let the trouts thrive in it. Summer temperatures in Melbourne (Australia) can hit 40+ a few days...

Would it be possible to turn of water to growthbeds if the temperature is over a max temp (say 40 degrees centigrate)

Cheers

Growbed pump control is on line 465. I have it set to turn off pumps during a configurable period of time and a configurable temperature. The only difference is that its written to avoid low temperature in winter. I have the opposite problem as you. The code alteration is very simple.



Would change to...



Example setting to make it work...
relay_pump_tempMIN would be set in the menu system for 40C
relay_pump_tempMAX would be set in the menu system for 38C or 39C
relay_pump_morningMIN would be set in the menu system for 11 hours
relay_pump_morningMAX would be set in the menu system for 18 hours
