Hi,
i just started working on a project "water level indicator with alarm using a microcontroller"
pls i need a good website where i will get the data i need and the schematic diagram for my project.
i have tried various websites but im not getting anything good out of them.

 

Take a look at the offerings here at Dave Johnson's website www.discovercircuits.com .

Go to Home Depot, they sell them for about $35. Most foundation levelers since Greco-Roman times use a most efficient method using just a tube with water.

labby,

I think the first step, before you get into schematics, is to define the details:
Water level in what: a tube, a tank, a river?
Indicating what: high/low, several discrete levels, continous range?
Indicating how: LEDs, LCD, analog meter, internet link?
Alarming when? Full, near full, near empty, empty?

Otherwise...its a battery, a float switch, a microcontroller, and a buzzer. And the microcontroller isn't needed...it's only in there because it was called for in the assignment.

Here is a schematic I found of a water level indicator
