Introduction
Data Acquisition (DAQ) Technology
|
|
|
Data Acquisition
(DAQ) is technology provides the link between the data-generating
sensors and data-storing recording devices. DAQ can also provide
the means for driving external actuators from a computer, by the
generation of external excitation signals. DAQ technology includes
both hardware and software.

|
| The
data usually need to
measure are - temperature, humidity, pressure, pH data, distance,
reflect, transparency, luminosity, light, anemorumbometer and clock
... etc. |
|
Sensors with analog
output have a standard for industrial or automotive output range
(0/4...20mV, 0...5/10V, 0,5...4,5V, more), current output usually is 0
- 20 m A. The Analog signal may be needed amplify The Sensor with
digital output is Hi, Low or 0, 1 or clock.
|
|
|
The task of data
acquisition hardware is to collect
incoming analog input signals and convert them to digital signals
for further processing and storage. Analog Input Specifications is
Number of Input Channels, Sampling Rat, Multiplexing, Buffer Size,
Range, and Resolution.
|
|
The Application is good for Industrial automation,
laboratory and science.
