Now that I have established my standard for sensor connections I will need build the hub to hook up the sensors.  So I build a 2 connector RJ45 jack hub to test the sensors that I build.  This hub will allow me to test different sensor configurations and arduino sketches for test sensors  as I develop them.

Here is what it looks like.

I have marked the terminals on both ends so there can be no confusion as to what connections are being used.  Make sure you have test all the connections with your multimeter.  That way you know for sure everything is working before you start testing situations with sensors.

I was asked by Make:SF to talk about aquaponic automation.  I have now developed a desk top unit to test all the sensors and arduino controllers.  The meeting will be held Tuesday March 8th in San Francisco.  I will have a working demo of the auto cycle of my controller working all phases of the aquaponic unit.  This will be a first for me as I have just completed the arduino sketch to handle the auto mode of the controller.

 

HERE ARE THE DETAILS:

SAFETY IS A HIGH PRIORITY  —

Water and 120 volt electricity do not mix….

Valve operates on 120 Volts

I have been searching for gravity feed valves for sometime now.  I will be using them to control release of water from my tanks with the help of an Arduino.  I picked the 120volt option on this valve so I would not to deal with 12 or 24 volt wall warts.  Everything I am using right now is 120 volts.

So I wanted to keep my prototype setup very simple and straight forward.  This does cause some safety issues, so being overly careful is always  a good thing.
