arduino -- Aquaponic automation development

Started by Rik Kretzinger. Last reply by David Leithauser Mar 27, 2017. 46 Replies

arduino's have a future in aquaponics in my mind.  Not many people talking about their use of arduino's and aquaponics.  Windowfarm groups are much more active with arduino's and control of systems. …Continue

This is a good addition to sensors for automation of aquaponic systems.  Got to order one and start to play with it.

NEW PRODUCT – 8″ eTape Liquid Level Sensor + extras

Etape8 Lrg

NEW PRODUCT – 8″ eTape Liquid Level Sensor + extras. The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. The eTape sensor’s envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed. This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid. The sensor’s resistive output is inversely proportional to the height of the liquid: the lower the liquid level, the higher the output resistance; the higher the liquid level, the lower the output resistance.

This is a very unique sensor, we haven’t seen anything else that is affordable and accurate for measuring liquid level. This sensor seems like it would be a handy addition to an hydroponics, aquarium, fountain or pool controller, or perhaps measuring a rain tube. This particular sensor is the 8″ model, we also include a 3-pin connector and 470 ohm resistor. The connector is so you don’t have to solder directly to the delicate pins: instead, just solder to the connector and plug it onto the sensor.

Since the sensor is resistive, it is easy to read it using a microcontroller/Arduino ADC pin. Check the tutorials tab for a quick-start pointer.

  • Sensor Length: 10.65″ (297 mm)
  • Width: 1.0″ (25.4mm)
  • Thickness: 0.015″ (0.208 mm)
  • Resistance Gradient: 55Ω / inch (22Ω / cm), ± 15%
  • Active Sensor Length: 12.6″ (320.7 mm)
  • Substrate: Polyethylene Terephthalate (PET)
  • Sensor Output: 700Ω empty, 85Ω full, ± 15%
  • Actuation Depth: Nominal 1 inch (25.4 mm)
  • Resolution: 1/32 inch (0.794 mm)
  • Temperature Range: 15°F – 140°F (-9°C – 60°C)

The future is a little closer:

Arduino water sprinkler control

TJ writes -

I made a sprinker system controller using arduino and your RTClib (thanks!). It has telnet features using a wiznet module to remotely control it and configure water schedules. I’ve also open sourced the code on github for anyone who’s interested.

Catching up on my BLOG reading and ran across this from "Arduino your Environment" blog by Steve Spence.

 

Dissolved Oxygen Sensor

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.
This is totally do able for auqaponic systems now.  I had been looking for a probe and how to connect up to an arduino.  Now it will take some work to figure out the sketch to run the arduino.

Hi,

 

I'm proud of John R. for his accomplishments in monitoring-controlling my Greenhouse in Bloomington, IN from his place in W. Lafayette, IN.  He put a Linux box in my house with a multiprocessor box with sensors in the green house and did a web tunneling thing which description i'll leave to him. 

 

We got our first data yesterday.  It is really an eye opener.  I expected to see more humidity inside than out.  And i see that i had little clue about the actual thermal behavior of a green house.  I based my views on my experience in Texas but they had swamp coolers running even at night and propane gas heat was relatively cheap in the 70's with oil refineries just down the road.  I think Texas' weather is more consistent than Indiana too.  I now think my notion of keeping just above freezing in winter was just a pipe dream, except to keep the worms alive.  Even if i did hold at 40F , plants' soil chemistry doesn't work below  45ish and not well below 60ish.

 

Outside humidity, temp sensor:

Happiness,

Homefire

Hi Terri,

 

Its really good to see you and so many others joining this group.  Your experience will be really useful and I appreciate the information about the mango software - it looks really promising.

 

I'm floored at the day job for the next four weeks and am struggling just to get my own ap system up.  I'm really looking forward to getting back at these projects since I have everything but time.

 

Good luck with your info. gathering and welcome!

Hi all, I'm new to aquaponics and I'm  still at the info. gathering phase.

My background is in water and wastewater treatment operations and I have used plc based process control systems for operating large scale water and wastewater facilities. I have a high level understanding of the various type of control loops used for monitoring and controlling process performance, i.e. dissolved oxygen, pH, solids & NH3/NOX concentrations; flowrates and other parameters.

 

I found this open source SCADA  platform that might work as the HMI called Mango - http://mango.serotoninsoftware.com/home.jsp

 

I know commercial  hardware/software is costly. I think it's great that there are hardware/software programmers interested in developing low cost systems!!!!

thank you . I checked it. problem solved.

If it is just this group you don't want to follow anymore, I believe you can do that from the e-mails from this group or over on the right under all the little member pictures  you can "stop following new members"
Comment by TCLynx on February 14, 2011 at 2:48pm

Tim,

In those e-mails there is a link where you can go to control the e-mails you are getting from the Ning site.

 

Or you may go to the settings link under your name over on the right side bar of the page.  Once there on the left sidebar, choose e-mail and change what e-mails you will get from the site.

stop sending me all these new people that joining!!!!!! it is over loading my email box!!!!!!!!!!! :-(
