Power Control Circuit Help

[Draco Rylos]

I did not know that Ironhead, thank you for informing me. My setup will be a two cell system. I am trying to design the circuit to control the pump and cell operation using 2 sensors that will also turn on a light when the water level in the cell gets low. I've got a lead of using an AND Gate and a NOR Gate, instead of the relays that I have in the drawing that was attached to an earlier post.

Yes, you can use logic gates, such as AND and NOR gates, but only for the logic part. Those logic gate ICs can't drive your pump directly, you will still need a power component, like a power transistor or a relay or a MOSFET or a triac to drive your pump. As far as I know logic gate ICs alone won't do.

The water itself is electrically charged . All you really need to do is have the positive side of an LED wired to the water itself and the negative to ground  when the level gets low the light goes out. If you want this to control another device  use a relay.

Or you can do a constant flow close loop system , run pump constant . With 4 LEDs connected to the water levels, when number 2 or 3 goes out its time to fill the main tank.

When you use constant flow the water always stays at  the right level to the cell stack as long as there is water in the system. Why  because the water is being pump through the cell to the top.This keeps amperage / HHO output stable. A 12 volt PC water cooling water pump will do the trick.

Did you look at the drawing attached to an earlier post man, I have 2 pumps, one pushing water into the cell stack from the tank the other is a recirculation pump. The recirculation pump draws water in from the upper portion of the cell and pushes the water in from underneath the stack. That, I hope, will aid in the extraction of hydroxy from the cell stack. The recirculation pump will shut down when the water level in the cell gets below the upper water level sensor. The one way valves after the recirculation pump and after the refill pump keep the water from being pushed out of the cell by the recirculation pump. Those are good suggestions, but I still want to use the circuit that I have designed but have been having trouble figuring out how to the the pump to turn off only AFTER it reaches the upper water level sensor.

sorry man . It was just a simplifying suggestion.
