what parameters are required for a programming of multi parameter controller which includes Temperture , Water level and Load current control?
what is the procedure for writing a program inside the mcu, and change in that program.

What you need are signal conditioners, ADC's, display, driver for your load current control, a good software for programming if not assembly and a microcontroller programmer.

If you want to outsource your project, you can PM me.

I suggest that the ADC used to be a multichannel ADC.

Why did you choose AT89C51?
Do you have a programmer to program it?
I don't think so, so better to start with microcontroller (also based on 8051-core) which can be programmed through their serial port, without external devices.
You can choose one like that from, for example, www.maxim-IC.com .
Other thing is to select proper A/D converter. Again, you can do it at Maxim, or other places..
It looks like for your purpose you don't need anything above 12-bit, and probably 10-bit A/D converter would be sufficient.

After you decide what exactly you would like to measure you can start selecting proper sensors, so let us leave it for a while..

As far as software is concerned, I would encourage you to start with assembly. This approach will give you full in-depth understanding on how a microprocessor works and how to control its internal/external memory, registers, inputs and outputs ..
There are plenty of links on the 8051 assembly (search this forum first), including thousands of examples, and I am pretty sure many of EDA members will give you plenty of valuable advices

It is better u make an emulator to write your program, so u can change it easily. Please visit www.pjrc.com
