What would work best on a cell to act as a water level sensor. I posted here http://www.overunity.com/index.php/topic,2634.0.html (http://www.overunity.com/index.php/topic,2634.0.html) about the water level sensor, but i guess no one noticed my last post and I decided to start a new topic about the water level sensor.
In your other thread I talked about using a connection to the water itself since it is charged to turn on what ever it is you need to turn on and off using a relay or whatever
. But it seems you did not want to hear that ,which is fine . I think a couple others made suggestions as well and you nearly flamed them and me .
This could be why your thread was left desolated .

If I did flame you, I apologize. I have been so focused on trying to get that circuit figured out, that I may have been a bit snappy.
Almost flamed lol . I understand , Its all good.
That's cool Ironhead. ;) The guy on http://www.electro-tech-online.com said to use 2 CMOS series chips 4093 (Schmitt Trigger) and a 4011 IC. I have attached a sample circuit that the guy that has been helping on electro-tech used to help me with my circuit setup. I'm still trying to figure out electronic circuits. I have been toying with electronic components for a long time, but have not really gotten into trying to solder together circuitry. All my interest in building my own circuits came with the discovery of this site and other alternative energy ideas.
Edit: I put the wrong image the first time I posted. hehe
I've encountered a similar problem and found this:

Yes, it's for toilets, but it can be easily adapted to any other water level sensor application. I'm personally going to use this. Good luck!
Hi,
First of all you'll have to know your logic voltage level, is it 3v, 3.3v, 5v, 9v, 12v or 15v ? So let's say you power your logic ICs with 12v dc, that means your logic 'high' would be 12v, and logic 'low' would be 0v.
Next, preferably to make things simple, all inputs only have 2 states, either ON or OFF (digital). From the schematics you've provided, inputs are active high, meaning a sensor should provide a 'high' signal (12v) when the water has reached it or when the water is higher (sensor submerged). When the water level is lower than a sensor, it should output a 'low' signal (0v).
If you use a float sensor that connects when water is at or above its level, and disconnects when water is below it, then all you gotta do is connect 1 pin of the float sensor to your logic input, while the other pin connects to your logic 'high' level (12v). To avoid floating the input logic, put a pulldown resistor at each input.
Ofcourse you can use other types of sensors, but what's important is that they work with similar logic.
Sorry bout the time between posts, i've been working and haven't had much time to post here on this board. My system will be running 12 Volts so my system would need to be set up for 'High' when the water is at the level of the sensors and 'Low' for when it is below the sensors, right?
