Windows based wireless data acquisition

Abstract

Nowadays, the global is transforming in to a new generation which makes the embedded system rejuvenates in order to keep abreast with the latest technology and innovation. As scientists, engineers and especially people of the world are having more task to be completed in a period of time and with limited income, that made mobility, time consuming, and cost effectiveness among the crucial criteria that must be emphasize in any upcoming project that will be develop. One major field which is currently being developed is the data acquisition system. It collects data based on the signals being measured. In order to meet the current technology, this project is aimed to enhance the current data acquisition system which features a wireless data transmission, small in size and affordable. It is also capable of displaying data on a Personal Computer (PC) using the conventional operating system, Microsoft® Corporation as the based station and on a Liquid Crystal Display (LCD) as a handheld device. The system starts with the analog signals detection from the transducer and then followed by the conversion data by the Analog to Digital Converter (ADC). This digital data will then being send to a microcontroller at the transmitter part for the wireless data transmission. Next, the data transmitted is received from another microcontroller at the receiver part and will be manipulated for displaying data in a graphical form on PC via Visual Basic® 6.0 software and in numbers on LCD. Thus, the output of this project will absolutely assist any end user to obtain data for monitoring and data analysis purpose.
