Abstract:The increasing capabilities of smart phones have led to the replacement of PC's in almost all real-time scenarios. A Smartphone is a mobile/portable personal computer with a swift processor, advanced mobile operating system, huge memory space and a platform for many real-time applications-business, accounting, entertainment, scientific, recreation, education, finance, social networking, news and many other applications suited to the 21st century impatient world. In the early inception of mobile technology development, mobile phones were elite devices primarily used by middle and upper class people. But with more and more Smartphones manufacturers entering the market, the price of a Smartphone is so affordable [1] that today about half the adult population owns a Smartphone.[2] Android phones are increasingly becoming cheaper [3], better and more intelligent. Android is a mobile OS developed by Google, based on the Linux kernel. [4] In this paper, we develop an android application which can monitor the realtime values of any electronic/optical/acoustic sensor on android powered Smartphone. The mobile application is well suited to the scientific community, engineers and professionals/amateurs in their real-time monitoring of sensed value. The stream of real time data is sent wirelessly to the Smartphone via Bluetooth or Wi-Fi. In this paper, we also present to you the ADLC model which includes feasibility study, Requirement analysis, Design and implementation, integration and testing, operation and maintenance and marketing.
