Today with the swift rise of WiFi and Bluetooth technologies, the wireless data acquisition network is becoming more and more a possibility. That is why; you find a number of users are moving towards a wire less system. The data acquisition system block diagram might look all the same as in the case of the wired system. That is so because; all that the wireless data acquisition network replaces is the wired network alone. It works exactly the same way only difference is that instead of transmitting over a wired network, the system would transfer the data over a wireless data acquisition network.
How does this work? In these systems, normally a transducer is fixed with a wireless capable transmitter. This transmitter will be in line with any of the standard communication protocol. There might be the WiFi or Bluetooth enabled transmitter embedded in the transducer itself. This would help the designers to get the signal from the transducer over a wire less system. In those conditions, using a standard WiFi or a Bluetooth is not possible since only digital signals could be transmitted over such networks. Therefore, these get transmitted as a RF signal. The RF signal is isolated and the value taken before making use of it at the destination point.
In the cases where the Analog to digital converter does the job of transmission, it is normally transferred in a digital mode. Under this condition, it is found that the standard forms of transmission carry more weight and it is also easy to use such data. The data would then ensure that the WiFi or Bluetooth is received using an appropriate design. In such cases it is also very easy and comfortable to provide a network since these devices also provide a plug out of its Ethernet port. This will bring the device in to the computer network without any issues. In addition to this, the software programming for capturing the input from such an Ethernet port is pretty easy as well.
You can build your own wireless data acquisition network using the relevant devices for these purposes available over the internet. There are sites that specialize in marketing such devices. Many of them have the capability to design and deliver the wireless data acquisition network depending upon your needs. On many occasions, the entire network is designed over a wireless platform. This is easier to do than the wired ones. Cost wise of course, the wired might be cheaper when you are investing into the equipments. But that is short run one; in the long run, the wireless data acquisition network will become cheaper and more comfortable to use. The reason for such a happening is that the initial investment in the wireless data acquisition network is to take care of the complete setup; since there is no involved hardware maintenance and these devices do not run through the process of maintaining such a job of network cabling, etc., There is also a reduction in the overall gain of the company in employing wireless data acquisition network.
