The idea of a smart grid enabling technologies used in recent years for the gain of full utility, customer protection, attracting a great deal of attention in the energy industry and academia. In continued growth of popularity and functionality by mobile devices, demand advanced mobile applications widespread in human life [1], [2].

      An attractive market for home automation and network of busy families and individuals will have physical limitations. ARDUINO and Wi-Fi shield, and it was the smart home micro web server. Arduino is an open source electronics proto typing platform on the basis of flexible, easy to use hardware and software.

Figure 1: Existing system of home automation system

An isolated WSN with one coordinator, which is integrated into the PLC transceiver, is established in each room. The existing system of home automation system is shown in Figure

1. The coordinator is responsible for transferring environmental parameters obtained by WSNs to the management station via PLCs. The control messages for home appliances are directly transferred using PLCs rather than WSNs [5]. The Figure 2 shows the proposed system of home automation system. The Arduino Uno and Wi-Fi shield were

   used to implement the micro Web-server for the Home gateway in figure 2. Home gateway connects to the Internet. Arduino Uno is an open-source microcontroller that uses ATMEGA 328, an Atmel AVR processor which can be programmed by the computer in C language via USB port. Arduino Uno also has on-board 5 analog pins and 13 digital pins for input and output operations, supporting SPI and I2C which can be used to interface with other devices. Figure 3 shows the hardware architecture and implementation. Any internet connection via Wi-Fi or 3G/4G network can be used on the user device [6]. The features that the proposed design offers are the control of energy management systems such as lightings, power plugs and HVAC (heating, ventilation and air conditioning) systems.

   1. HOME AUTOMATION DEVICES

      Central controller (Arduino) receiving commands used to perform. You may connect to the Internet through a Wi-Fi shield mounted on the Arduino. On the user side, provides a portable interface to the system as a whole through an easy-to- use application. Can either be wired mobile device of the central control unit (through the USB cable, for example), or in connection with this wirelessly. Within the home, wireless connectivity can be achieved by using the Wi-Fi shield on the central console. This way, you will be able to access the console, either locally or remotely through the Internet. In this

      case, client/server architecture is the one to choose, because the central console as a static entity that responds to requests from clients. Figure 4. shows the whole process Smart home automation system. Hence need for server (at the application level, any piece of code that cn respond to client requests) is closely linked to the company. We'll use a simple Web server application running on Arduino that communicates via HTTP protocol with Web-based Android app [7].

   2. INPUT /OUTPUT BLOCK

      Input/output block consists of two pieces of PIR (Passive Infra-Red) motion sensor and an LM35 temperature sensor as inputs and some lamps, sockets, relay and buzzer as outputs.PIR sensor is used to detect the presence of motion. The sensor readings are used to turn off the lights if there is no activity and turn on the lights otherwise. In addition, this sensor is also used for security systems to detect suspicious movements. If it detects any suspicious movement an alarm (buzzer) will sound. An LM35 is functioning as temperature monitoring. This sensor also serves as an input in order to execute some sockets. The socket will in on condition when the temperature exceeds a certain limit. This condition will activate a fan or Air Condition (AC) while connected to the socket. Connection circuit between microcontroller system with a PIR sensor and an LM35 sensor is Shown in Figure 5 and Figure 6. Output part consists of the relays and buzzer. Buzzer serves as a warning alarm when there is suspicious movement. Relays connected with lamps and socket [8].

      1. Automatic Lamp control

         Figure 5: Connection Circuit with PIR Sensor

         In this project gives the intelligent operation for lamps and fans. Here the system is connected with temperature control and lamp control. Light dependent resistor (LDR) and

         Temperature sensor (LM35) are the main components for this automatic control of lamps and fans. In Figure 5 shows

         connection circuit of arduino with PIR Sensor for lamp control. Here the LDR is responsible for lamp control and LM35 is responsible for controlling the operation of fan. In lamp control, LDR values are previously set. Then the darkness falling on the LDR due to sunset. The microcontroller receives the resistance value from LDR. When the controller attains the limit, the lamp will glow, or otherwise it will turn off [9].

      2. Automatic Fan and AC control

      Figure 6: Connection Circuit with LM35 Sensor Automatic fan and control circuit connection is shown in

      Figure 6. In fan/AC control, the temperature values are previously set. During daytime, the temperature values are about 35oC.Then the microcontroller will receive the signal from LM35, and turns ON the port, which is connected to AC/fan. During winter season, the temperature reduced as below 20oC.Then there is no need of fan/AC. Hence the fan/AC will turn off.

2. Wi-Fi Shield

   Wi-Fi is an open global standard built on the IEEE

   802.15.4 MAC/PHY. Wi-Fi defines a network layer above the

   802.15.4 layers to support advanced mesh routing capabilities. The Wi-Fi specification is developed by a growing consortium of companies that make up the Wi-Fi Alliance. The Alliance is made up of over 300 members, including semiconductor,

   module, stack, and software developers in Figure 12. [11]. Wi-

   Fi Series 2The difference between Series 1 (S1) and Series 2 (S2) is that the latter enhances the power output of the antenna to 2mW [11]. S2 also enhances the data protocol of the Wi-Fi module.S2 is similar to S1 in enabling simple and easy communication between microcontrollers and supporting point-to-point and point-to-multi point communication [12]. The connection diagram of esp8266 is shown in Figure 8.

   The function of the relay module as normal switch "ON" and "OFF" will turn a lamp. An infrared detection system consists of infrared sensor as an input, while the relay module as starting Arduino Wi-Fi adapter. The Wi-Fi is a feature-rich RF module for use on a wireless sensor network. The IEEE 802.15.4 protocol greatly reduces the work of the programming ensuring data communications. The Wi-Fi has many other features for use in a WSN beyond its networking ability [13]. Figure 11 shows the system overview of the home automation system. The web page on hosting server can read and update data in database. Writing the Code for the Web Client For the Web-enabled light switch, we will create a simple Ruby on Rails project to manage the user interface interaction first via a web browser. We wont spend a lot of time on the user interface.

   Since that will ultimately be the job of the custom Android application we will create after the web interface is functionally tested.The Android app was designed to show the switch is the same as the web page on hosting server. It can also read update data on the database by touching the "ON" or "OFF" and appears on the button as on the website. This smart switch device, the lamp in a house controlled manually with
