hi, i m looking for a simple and precise circuit for my overhead water tank. it will sound or light when water is higher over any point to prevent overflow.

similarly same can be done for water going down some point for alert to fill the tank again, thanks bye.. aamir khan

Don't really need a circuit to detect this. A simple float control would be fine. Check your local Home Depot or hardware store. So many things use float controls from toilets to bilge pumps, you can probably find something build for yoru needs already.

You can also get completely passive float-controlled valves and do away with the alarm and lights. They are used for, among other things, filling stock watering troughs. I don't know your water or materials supply situation or the freezing risk, but you could probably easily adapt a toilet tank fill valve to the task.

awright

 

Arun,
What do you need it for?

RV tank indicators would be off the shelf and would have the indication you would need.
