The present paper presents a Data Acquisition System (DAS) set up and implemented in our laboratory. Its main purpose is to collect distance data offered by a set of mobile sensors with different geographical locations. By using the GPS and GPRS techniques, DAS gathers and processes both the data from sensors and the GPS coordinates of the locations. DAS is composed of a central data base (CDB), resident on a PC connected to the Internet and a number of distributed mobile data bases (MDBs), resident in the data acquisition mobile equipment (DAME), which communicates with CDB via GPRS. Accessing CDB, through a “client-server” application, enables presentation on a GIS map of the coordinates of mobile locations and presentation, in a tabular form, of the data collected from the sensors corresponding to each location.
