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
