Create a Wireless Network for Data Acquisition

The process of Data acquisition involves the acquisition of signals and processing these signals to get the desirable data. Wireless data acquisition network is becoming popular now-a-days because of the quick increase in WiFi and Bluetooth technologies. The increase of these technologies allures more and more users to the wireless system. The block diagram of wireless data acquisition system is almost similar to that of a wired system and because of this the wired network is replaced by the wireless data acquisition network. Both the system works in a similar manner. The only difference between them is that in a wired network the data is transmitting through a wired network and in a wireless network, the system is transmitting data through a wireless data acquisition network.

Let us consider the working of these systems. Generally in these systems a transducer is attached with a wireless transmitter and this transmitter will work with any standard communication protocol. You can also find transmitter with WiFi or Bluetooth with in the transducer that enables the designers to receive signals from transducer attached to the wireless system. In such situations, it is not possible to use a standard WiFi or Bluetooth data acquisition system as it can transmit only digital signals over such networks and because of this the data will be transferred as RF signal.  RF signal is secluded and the value will be measured before using it at the target.

If the transmission is from Analog to digital converter, the data will be normally transmitted as digital signals and in this condition, the standard transmission carries more weight and such data can be used easily. The data then ensures that the WiFi or Bluetooth is receiving signals with the help of a suitable design. As WiFi or Bluetooth provides a plug out from their Ethernet port, it is easy and comfortable to provide a data acquisition network. The device can be connected in to the computer network with the help of Ethernet port with out any problems and you can also capture the input from this kind of Ethernet port easily because of its software programming.

By using appropriate devices available on internet, you can create you own wireless data acquisition network. Such devices are marketed by some specialized sites and most of these devices can design and deliver wireless data acquisition network according to your needs. The whole network is designed on a wireless platform in most of the cases and it is easier than the wired systems. The wired system is cheaper than the wireless system when thinking about the investment on equipments. But of course, the wireless system will become cheaper and comfortable to use in the long run. The reason for the initial investment of wireless data acquisition network is that you have to take care of the setup completely. As there is no hardware maintenance involved and these devices do not run during the process of maintenance, there will be a decrease in overall profit of the company while using wireless data acquisition network.
