Project synopsis
Project Title:
2. Designing of a Low cost Data Acquisition Card (DAQ).
Project Aim:
The main objective of this project is to design a
microcontroller-based, low-cost and multi-function data
acquisition card. Many kinds of projects in
Universities need data collection interfaces which greatly
increase the cost of project.

3. Introduction:
Using computer technology in the developing world,
are becoming increasingly common. Computers are
used in all areas of our lives with these developments.
In many control applications performed with
computers, the computers’ communication with the
external environment is very important.
• Data acquisition (DAQ) is the process of measuring
an electrical or physical phenomenon such as voltage,
current, temperature, pressure, or sound with a
computer.
• Data acquisition cards are needed in computer aided
analysis or control applications.
• A typical commercial DAQ card contains ADC and
DAC that allows input and output of analog and digital
signals in addition to digital input/output channels.
4. • In card design, PIC16F877A hosting several
integrated units is used.
OVERVIEW OF THE PROJECT:
Hardware Diagram
6. Methods:
In design, PIC16F877A, a microcontroller of
Microchip company, is used to provide
communication between computer and data
acquisition card and to control ports. Commands,
received from computer, are analyzed and
responded continuously in a loop. If microcontroller
receives a command, firstly analyses that and then
performs the request.
SOFTWARE USED:
• µVision Keil (v4): µVision Keil (version 4) provides
IDE for 8051 programming & is very easy to use.
When starting a new project, simply select the
microcontroller you use from the Device Database
and the µVision IDE sets all Compiler, Assembler,
Linker, and Memory options. It’s device database is
large which supports many ICs of the 8051 family. A
HEX file can be created with the help of Keil which is
required for burning onto chip. It has a powerful
debugging tool which detects most of the errors in
the program.
7. COMPONENTS USED:
• MAX1241
• MAX232
• ADC5621
• 555 Timer
• Microcontroller 74HCT573
• PIC 16F877A
