Abstract - Nowadays, most of the work is based on
computer and laptop as technology has become one of inseparable part of our life. In conventional system method for controlling the electrical equipment, the person has to use switch boards and they are placed in one particular place. So every time we have to go there and control electrical equipment by turning switch ON and OFF. It is time consuming and energy consuming task to control electrical equipment. To save the time and man force, the system is designed to control electrical appliances using Wi-Fi and laptop. In most of the offices or at any work places Wi-Fi is easily available. It can replace conventional ON/OFF system of electrical appliances. We are introducing a new mechanism so that the laptop can be leveraged to communicate with ARM7 processor and control the electrical appliances. Software application is created which will be installed on laptop so that person can control the electrical appliances by sending commands through software. Laptop is use to send the commands through Wi-Fi module. Wi-Fi module is used for Establishment the net connection through RJ45 connector. The microcontroller used is LPC2148 controller of ARM7 Processor family. Therefore according to the requirement person will send the commands from LAPTOP. Then the devices will be controlled through Wi-Fi module. This allows a device to wirelessly provide data to the system & reduces the manpower for operating the devices every time. Thus system provides flexibility; reduce manpower & less power consumption [1, 3]. Key Words: Wi-Fi module, Laptop, Embedded system, RJ45, ARM 7.
1. INTRODUCTION An embedded system is a special and multipurpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer, such as a desktop computer, an embedded system performs one or a few predefined tasks, usually with very specific requirements. Personal digital assistants (PDAs) or handheld computers are usually considered embedded devices because of the nature of their hardware design, even though they are more expandable in software terms. The concepts of embedded system are used to develop a System named “ELECTRICAL APPLIANCES CONTROL USING Wi-Fi AND LAPTOP”. [1] Electrical appliances automation is equipped with special facilities to enable occupants to control or program an array of automated devices. For example, Supervisor on vacation can arm a security system, control temperature gauges, © 2017, IRJET

switch appliances ON or OFF, control lighting, and perform many other tasks. Our main focus is to control the electrical appliances in place. The motivations behind the goal to control of electrical appliances are simply and easily. It’s not always feasible to be physically near to the electric switch board still sometimes it’s very important to control the appliances for many purposes. So the controlling the electrical appliances through Wi-Fi takes the control of the electrical appliances from the hands of the people. If a simple Wi-Fi and laptop takes the added responsibility to control the electrical appliances then the control is reachable from almost everywhere people who is present in that room or place. EMBEDDED wireless sensor networks (EWSNs) consist of sensor nodes with embedded sensors to sense data about a phenomenon and these sensor nodes communicate with neighbouring sensor nodes over wireless links. Many emerging EWSN applications (e.g., surveillance, volcano monitoring) require a plenty of sensors (e.g., acoustic, seismic, temperature, humidity and image sensors like smart cameras) embedded in the sensor nodes. Although traditional EWSNs design with scalar sensors (e.g., temperature like LDR, humidity) transmit most of the sensed information to a sink node (base station node). For example, consider a military EWSN deployed in a battlefield, which needed various sensors, such as imaging, acoustic, humidity and electromagnetic sensors. This application presents different challenges for existing EWSNs since transmission of high-resolution images and video transmitted over bandwidth-limited wireless links from transmitting nodes to the receiving node is infeasible. Although, meaningful processing of multimedia data (acoustic, image, and video in this example) in real-time exceeds the capabilities of conventional EWSNs consisting of single-core embedded sensor nodes, and requires more powerful embedded sensor nodes to realize this application. [3] This sort of high end technology is supposed to facilitate the various life easing utilities to a new age and bringing things out of the box to as near as one’s fingers. There exists a number of available media for remotely communicate. Wi-Fi is a good example of this type of communication. Internet places virtually no bounds on geographical placement and is thus considered “enough” remote by our definition. So we are using Wi-Fi module for controlling the devices as per requirement of supervisor in the industry. [2]
