Data acquisition system project is a fine combination of analog and digital electronics. This project is designed so as to fulfill the requirements of the industry applications, home applications. The project consists of parameters monitoring, parameter storage. PC interface is one of the main features of the project in which various data like value of parameters, date and time are sent to the PC.

We have used Microcontroller as a main component of the project. Now a Microcontroller has become a main component of many of the electronic circuits. Also Liquid Crystal Display (LCD) and EEPROM is used on major basis for the display and storage purpose. I2C bus protocol is used while interfacing 8051 with EEPROM. This project which will consist of two basis modules. First is “Data Monitoring” & other is “Data Storage”

A display unit will show the value of parameters. This will help for the person to know the values, for this purpose we are going to use various sensors, which will be connected to ADC.

The other module is named as parameter storage. It can be used to store the parameter values in the memory. We are going to use EEPROM memory IC. These values can later seen using a keypad provided on the front panel. This system is useful as many times its difficult to measure the parameter values manually and also this module is more accurate than the domestic system.
