Hi,

I'm in the middle of building a microprocessor based system that monitors temp, pH and light levels, and allows the control of heaters, Co2 solenoid, water changing solenoids, and two banks of lights.

What other things do people think would make this more useful?

Thanks for you input.

Matthew

I have a rena timer about 30 years old on one of my tanks. turns lights on and off,turns off airstone and feeds fish up to 4 times daily. It works very well and I don't know if they are still available. All works off the mains.

Hey Matthew

Will you be using it in Marine or Freshwater setups?

how would you make one of those?

foufee, will you have any problems getting the parts in China where you come from??

You don't live in China?

Oh !!

Try going up to profile, just below the top advert banner above,

click on that and fill in the field, six down in the profile section.

Says Location or something like that.

Will you be making this processor accessable away from the area, like overseas etc, so as you can do adjustments if possible?

Check with Warren, to me he has a very commplicated system with his tanks.

Not any more. I got rid of that system now I'm only running one tank. It wasn't that complicated Alan, it was just an automatic dosing system to treat the RO water to add the right balance of salts on the continuous waterchange system.

Warren, to me, getting a new TV to oerate anywhere near correct. is technical for me.

Now I'm expected to wire up my stereo thru it too, and hope that works???

Yeah well!!

continuous water change system? now that sounds great!

The system is based on an AVR (www.atmel.com) 8 bit micro processor, the solenoids (water and Co2) have been canabalised from washing machines and an incubator (but they can be bought from various places around as components). The user interface is currently a 80x8 character LCD display, and the front panel from the incubator.

The temperature sensors are 10 bit 1wire sensors, and the light levels are sensed using a LDR.

I'm going to be using it for a freshwater system.

At the moment, there are no plans to add internet connectivity to it (but it's not impossible).

Oh, I've also filled in where I am (the Wairarapa).
