A. Zoric, D. Perisic, S. Obradovic, P. Spalevic. Virtual Multisensors Data Acquisition and Analysis System Design // Electronics and Electrical Engineering. - Kaunas: Technologija, 2011. - No. 10(116). - P. 49-54. The hardware and software solution of the virtual multisensors data acquisition and analysis system, intended for more laboratory setup is described in this paper. The system uses recently developed digital and analog integrated sensors for acquisition of temperature, relative humidity, ambient light level and atmospheric air pressure. The system also calculates and displays the pressure altitude and the kind of the light as well as depicts the dew-point waveform. Communication between the acquisition hardware and PC is established via USB port of the PC or precisely by emulating RS232 over USB. At the same time the power lines of the USB port serve as power supply lines of the acquisition hardware. Due to the precalibration of the recent sensors, expensive system calibration procedures are avoided and thus the cost of the system maintenance is reduced. The graphical user interface (GUI) is realized under LabView 7 Express integrated development enviroment. III. 4, bibl. 10, tabl. 2 (in English; abstracts in English and Lithuanian).
