The Low Cost LabVIEW Wireless Instrument

Abstract

This paper proposed low cost instruments for wireless communication based on LabVIEW program. Conventional monitoring and controlling method using LabVIEW need several unique devices including data acquisition card (DAQ), RS232, wireless data acquisition (WDA), the serial and parallel interfaces which lead to expensive cost and complex system. This paper explains the new design of wireless interface devices which uses Wi-Fi USB, MCU board, and RS232 using LabVIEW to save cost. The objective is to develop low cost and easy tools for wireless monitor and interface. Five cases are considered including LED, traffic light, stepping motor, DC volt meter, and temperature data logger on the IEEE 802.11 standard. The experiment results show the developed programs which can remote instruments on a monitor accurately.
