I want a circuit for water sprinkler which can be interfaced with the microcontroller and can be automated by programming.

No, it's just for a project purpose.
I want a circuit which is interrelated with soil moisture sensor.
The idea is such that when the water level in the ground gets low, the water sprinkler starts to sprinkle the water until it reaches the sufficient level.
This kind of circuit i want.
I tried a lot, but i was unable to make one.

I advise that you can read some information about:Embedded micro-controller and processor design,maybe it can help you.

If the soil mositure is low thn mcu will turn on the sprinkler pump, if moisture is ok then sprinkler pump is turned off. right?

No,

The circuit is what you want. Actually it shows relays to control the water sprinkler pumps. The pumps are not shown. It uses LPC mcu you can use any mcu.

A certain amount of current flows through the probes and it is converted to voltage in the range of 0-5v and given to mcu ADC i/p. It is calibrated for certain value so that the pump turn ON at a specific moisture and turn OFF at another specific moisture.

I don't have the circuit, but I have asked its author to send me the circuit. Hope she send the circuit.

What probe do you want to use? Do you have any specific probe to be used?

Project files, source, circuit (jpg and Eagle, ...) all are on that address link of project, you just need to download files on your local PC and open ZIP archive files.

If you have the circuit then post it, so that it can be interfaced with mcu and relay and other components can be implemented in the circuit.
