Description Data acquisition is the process by which events in the real world are sampled and translated into machine-readable signals. Data acquisition typically involves sensors, transmitters and other instruments to collect signals, waveforms etc. to be processed and analyzed with a computer. The components of data acquisition systems include appropriate sensors that convert any measurement parameter to an electrical signal, which is acquired by data acquisition hardware. Acquired data typically is displayed, analyzed, and stored on a PC. In our project the Temperature data was monitored by using the Microcontroller & PC. The Project has an Inbuilt Data logger which is used to Log the Temperature data on the PC. A data logger is any device that can be used to store data. This includes many data acquisition devices such as plug-in boards or serial communication systems which use a computer as a real time data recording system. The Microcontroller AT89S52 has 8K Bytes of In-System Programmable (ISP) Flash Memory.

its easy to make interface like this... the only thing is... receive the data via serial and update the software interface one by one, you can do update after some interval. there are many serial example available online.. please try once.. and use forum for next..

Thanks ajay i tried a lot but couldn't succed.

Actualy i want temperture controller in which the limits can be changed dynamivcaly on the 89S8252 eeprom adresss say 0x200. so we try to send the data serially from vb application but i ma not able to write the correct values.

It may be to do some thing with serial because when i write this in 89s8252 it's working fine(through program not through serial). Can u help.

better take the discussion in forum because its comment area.
what you can do is.. write the value in RAM instead of ROM. so easy to do with serial i think. Rest we can discuss in forum. Just create a new topic in "Project additions and changes" Forum.
