MONITORING AND CONTROLLING OF ELECTRICAL MACHINES AND ELECTRICAL APPLIANCES BY USING WI-FI BASED ANDROID APPLICATION

Abstract

“Android” is the world’s most adopted mobile stand which is means for creating application that look great and take advantage of hardware capabilities. The advantage of android is that it is an open resource working system is used in provisions of mobile application that is smart phone which will perform as a remote controller. Here the proposed system is measured to controlling and monitoring Machines and Electrical Appliances using android application where the slightly controlling and monitoring is achieved. Android mobile act as a transmitter and the acknowledged by Wi-Fi Router receiver interfaced to AVR microcontroller of 89S52 well-known is an superior edition of 89S52 microcontroller. Every time data is sent by android application as per code written is executed by AVR to distribute supply signal to triac through optical segregation. Hence the power to load associated in series with triac is controlled based on received signal and speed control of machines is achieved. Apart from Speed controlling and monitoring, we also monitoring the a variety of Electrical Appliances like Fans, Lamps, opening and closing of Entrance gate, and detection of leakage of LPG gas in industry. User can control all applications from a single Android Application in their Smart phone. KEYWORDS: Wi-Fi (wireless fidility ,AVR (Advanced.
