Hi Shahul,

I need to do a data logger project.

Is it a college project or it is to be used in the industry. If it is an industrial grade project, you will have to first get the information about various test certifications , and information about the environment in which it will be used.

We have sound knowledge on 8051 and programming


All the features that you mentioned can be achieved using MCS51 family processor. Now let us look into each of the features that you mentioned:

1: LOCAL DISPLAY UNIT (Graphical)
You have various options: LCD128x32, LCD128x64,....Select the size of LCD.

Shahul Mydeenali said:
2: That data should be monitored on the PC (real time)
So you need connectivitiy with PC : wired or wireless..you decide. Do you intend to use standard freely available softwares on the net, or do you want to write your own software on the PC Side?

Shahul Mydeenali said:
3: The IO pin should be extended.
Which IO pin is to be extended? You have not mentioned any IO pin...or are you saying that the wires that go in and out of you datalogger as IO pins? Or are the wires that connect to the valve and other sensors? If so, then we need info about each of them.

5. Local memory for log
How much amount of memory? 1kbytes, 10kbytes, 100kbytes, 1 Mbytes, 10MBytes, 100MBytes...?(All these are possible using MCS51...for large memories, you can use MMC Cards in SPI Mode.) What type of memory: Flash, Battery backed, pluggable.....?

Shahul Mydeenali said:
6. Wirless data transfer between system (PC) and board.
What is the distance between PC and datalogger? What is the size of data and what will be its update rate (how fast do you want data to e seen on the PC?...milliseconds, Seconds, several seconds?

Shahul Mydeenali said:
7. Controlling from remote location
Once you have established the connectivity, you can do this very easily.
