Data-acquisition systems are used to collect data regarding the system performance for evaluation purposes. Most present data-acquisition systems collect the data of interest and store them in a local memory until the system operator downloads them to a computer. In this paper, the development of sensor-based microcontroller data acquisition system is designed and described. The proposed system records directly the data on a CSV file, though it has the ability to use a PC or Ethernet. The present system shows a stable and consistence results and has the advantages of rapid development and flexibility in the case of changes.
