Nixu's Aquarium setup (Work in progres)

[niksunen]

Wow! Nice work! I can hardly wait to see the final results.  Sure beats using a Kill a Watt meter.

Will you be able to monitor anything that's directly plugged into the Robo Tank outlets? What about the additional 8 outlets? I'm almost afraid to know how much power my tank consumes ;-)

Keep us posted!

Yeah thats it how i planned it to working, it meter anything which is connected to powerbar outlets, so i have to make little modifications to the powerbar. But it meter all equipment, i don't even try to meter each outlet individual, because that is too "complex" (yeah it can be done, but i have to "build" meter circuit every outlet, and code will be much bigger, so i don't even want to do that )  

basically i add that kind of current transformer (but only 10 amp, because aquarium don't use 100 amps )  to wire (which is going from wall socket to powerbar) and it measure current (of course it needs a little bit electronic parts also, but nothing much) 




And also i need to meter ac voltage, and when i have current and voltage, rest is math  :)

There is page, where i found idea of it. And there is also library that i use, and electric diagram. (it is pretty simple)
