Important Things to Know About Data Acquisition Systems

DAQ accessories

Mostly used by engineers and scientists, data acquisition is a process of measuring physical conditions of the environment and converting the data into numeric values. In general, data acquisition systems or DAQ systems are composed of sensors that are responsible for electrical signals, a signal-conditioning circuitry that converts electrical signals to digital values and analog-to-digital converters responsible for digital values as well.

Uses of DAQ Systems

Data acquisition systems are popularly used by engineers and scientists in their laboratories. With DAQ, testing and measurement of data becomes much easier for industries involved in food processing, oil refining, manufacturing of chemicals, production of cement and textile and many more.

DAQ systems are used to measure the following energy:

  • Mechanical energy such as velocity, acceleration, force, displacement, etc.
  • Thermal energy such as heat.
  • Electrical energy such as current, power, voltage, etc.
  • Chemical energy such as pH.
  • Radiant energy such as radiation for infrared, nuclear, etc.

Aside from the fact that DAQ systems serve well in their function as a bridge between the real world and the digital world, they are also employed because of their cost, accuracy, and simplicity.


  • There is decrease in the cost for in entering, retrieving, and storing data.
  • There is a higher accuracy rate and reduced possibility of errors.
  • There is a reduction in cases of redundant data.
  • The data security is significantly more secured.
  • The users have easy access to the data.


  • The damage of the database may affect the programs.
  • There is a need for users to be trained for the system.
  • There are start-up costs for the hardware and software.

how wireless daq works

Going Wireless

So, it’s not just iPods or laptops taking advantage of the modern technology, DAQs are int he bandwagon as well.Traditionally, data acquisition systems had cables and wires attached to it. However, with the advancement of technology and the introduction of wirelessness, wireless data acquisition systems have slowly taken over. The reason why wireless DAQs have bombarded the market is because it offers a lot of advantages. A few of these advantages are the following:

  • Battery Power

Wireless DAQs can stand-alone for up to 9 hours or so. They can easily without the need for power supply. This is an advantage if the DAQ system needs to be in a location where no power supply is available.

  • Mobile Data

The sensors for a wireless data acquisition system is actually suitable for mobile use. So, if you don’t want a big computer or laptop screen around, your phone is also qualified.

  • Time Efficiency

With no more cables and wires needed to be plugged in and with the fast installation of sensors, scientists and engineers will definitely save time in their projects.

  • Multiple Capability

Wireless DAQs are capable of multiple channel and measurement location.

  • Remote Location

Since the system is wireless, it can easily be installed to areas which are difficult to access. This widens the area of coverage for engineers and scientists in their studies.

Indeed, wireless DAQs are a great choice if you’re looking for something that’s efficient, convenient, and effective. If you’re interested and looking for more Wireless DAQ options check out
