Arduino based tank controller

[Vancouver Reefer]

Hi Guys,

I have been making quite abit of progress on my controller so far. Infact i have run out of I/O and memory, So i found this little guy to upgrade to:

They are fully compatible with all the arduino code and are great for a larger controller.

My controller is currently at the following stage:

ATO
Automatic water changer
Tank temp
led lighting with sunrise and sunset
PWM cooling fan control
flood sensor
heater and chiller runaway cutoffs
alarm
LCD
Real time clock

To be finished:

PH and salinity circuits for tank and fresh salt mix
4 head perilstatic doser
Internet GUI Text message alarm notification.


Please see my link at the bottom of the page for a little idea of what i got up to at the start of this project. Now i have gotten a new job i now have the finances to get back into this full swing!!

If anyone has any questions please feel free to ask and ill see if i can help out!

I have been looking for awhile for a circuit for measuring Salinity....have you found one or designed one....I believe it works on the same principle as ph and orp, but am not sure!

Hi Kevin,

I have found this one:

I have still yet to build it, but the guy who designed it has built and he seems to have it working good.

My parts are on order so i will be able to play in the next month or so when i get round to it. Let me know how you get on if you build it before me.
