WHAT IS DAQ??

• Data Acquisition is the sampling of real world data

• It is the national instrument which measure the physical data and convert that data in digital form.

• That digital form is calculated by transducers/other sensors.

• Process, analyze, store, and display the acquired data with the help of software

SHORT HISTORY

• First in 1963 it invented it's call by IBM 7700 Data Acquisition System

• IBM 1800 Data Acquisition and Control System.

• In 1974 S-100

• In 1981 IBM Personal Computer and Scientific Solutions it was the first pc data acquisition system

COMPONENTS OF DAQ

• Each data acquisition system has unique

functionality to serve application- specific

requirements, all systems share common

components that include,

• Signals & sensors

• signal conditioning

• DAQ hardware

• computer with software.

SIGNAL PROCESSING

• Electrical signals are conditioned so they can be

used by an analog input board. The following

features may be available:

Amplification

Isolation

Filtering

Linearization

WHY WE USE OF DAQ ??

• Collecting data from in any physical component is very time consuming process

• But by the use of DAQ system it allows the automatic data collection and made it easy.

WHAT IS DATA LOGGER??

• Data logger is an electronic device that records data

over time .

• It is located either with a built in instrument or sensor

via external instruments and sensors.

• digital processor

• They generally are small, battery powered, portable,

and equipped with a microprocessor

SHORT HISTORY

First data logger was a CR7.

It was basically invented 28 years before today.

Then made improvement

Data logger is a device which is used for

measuring the data

like; if we want to measure the temperature of

railway rail the data logger is attached at various

distance and by the computer device we can see

and compare the whole temputere.

TYPES OF DATA LOGGER

Mechanical data logger

Electronic data logger

Wireless data loggers
