Abstract — Smart homes refers to energy efficient, time saving includes reduces the human efforts. Commercial content distribution network (CDNs) has Video-on-demand (VOD) services for on-demand capacity provisioning on smart television (Home Automation). The content has full control and customization, so they prefer self- managed content infrastructure. The initial capital investment for physical infrastructure was so expensive and quite difficult for management. The objective of key providers was to reduce the server rental cost by accessing through the efficient and inexpensive ESP8266 chip to the cloud platforms on which dynamic server provisioning to reduce the server rental cost which was the key objective for content providers. In this paper we addressed the challenges of reducing the cost of accessing the cloud platforms. We present the construction of ESP8266 with the Arduino or microcontroller are attached to get the smart television, where all our choice of videos can be stored and retrieved at any time. Adafruit, Electrodragon, Sparkfun helps to get the chip. Through the software development kit (SDK) in ESP8266 that allow the chip to be programmed which remove the need of the microcontroller. Generally accessing cloud facility will produce high cost but in this paper gives the replacement of the accessing the cloud with the ESP8266 serial chip which operated in low power consumption with the low cost because it has the three configurable sleep modes. Keywords — Automation; E SP8266; Sensors I. I NTRODUCTION Home automation is commonly called smart home [1]. It involves the control and handle the things like light, fan, door, alarming for certain remainders, security purposes etc. All the things are connected to the internet and all of them can accessed at any place and any time. Most popular protocol communication for the products include X10, Ethernet, ZigBee and Z-Wave, or other protocols [2] are all incompatible with other . The web server is simultaneously updated by sensing the status of the things which are connected to the network. The status of the appliances is controlled by the switch it either ON or OFF using the computer technology. It also provides the security, energy efficient [3], and ease of use, hence it is adopted more. It also helps by providing to control and monitoring on web browser. The main

objective of the project is to help handicapped people and aged people by alerting in the critical situations. All the devices can be used in our own sitting place itself. The problem overcome by this paper is about that home automation is generally implemented by using Bluetooth through our PC. Pin check algorithm is used to implement this set-up by using the cable network other than the wireless communication. The device ESP8266, which is the embedded device used to access the cloud. The home automation using Bluetooth with the help of PC has implemented by N.Srikanthan [4].The range is limited by using the Bluetooth device. The devices are controlled by the telephone and with PIC controlling remote device by Hasan [5]. The IOT devices uses different types of protocol. MQTT (Message Queuing Telemetry Transport) is one of the useful and advance. Because it is easy to implement, open, lightweight, low bandwidth protocol. We can also use PIR sensor and proximity. Where the devices in IOT is used for controlling or nominating the devices where all of them are far away from this. MQTT and TCP protocols are also used to implement the ESP8266 Wi-Fi module. The potential IOT applications develop the environment that covers all together the applications, command, control and routing process and security of the node and system. All the IOT devices include various objects like personal computer, smart phones, tablets, which gives the communication between the things and people and also the things between them [6]. To reduce the need for the home intervention, we are used to control the home automation through the use of control systems [7]. II. PROPOSED SYSTEM ESP8266 (currently ESP8266EX) is a chip which is a highly integrated Wi-Fi SoC solution where in the Internet of Things industry, the users overcomes the efficient power usage efficiently, design and performance also provides networkable foundation of networkable foundation for facilitating end-point IOT developments. The vendors repeatedly created the ESP8266 chip at their cores includes multitude of modules. As well as the Olimex, Adafruit, Sparkfun,

WeMos, ESPert (ESPresso) all make various modules. ESP8266 can act either as the slave to a host MCU or as a standalone application. When it act as a host, it promptly boots up from flash. The high speed cache helps to increase the system performance and the system memory gets optimized A. Home Automation The ESP8266 with on board Wi-Fi capabilities and also has integrated processor. Acts as an perfect chip for Home Automation field. In this paper we are going to use the Adafruit HUZZAH ESP8266 breakout, which will be easy to use in the ESP8266 breakout board and two components such as a sensor module and a lamp controller. We can able to control the small home automation system anywhere in the world through Adafruit IO. Fig2:server (cloud network)

a) Modem-Sleep: When the chip is connected to the router in the station mode, the Modem-sleep mode is activated. The connection is enabled by the DTIM beacon mechanism. Here, the power is saved when the Wi-Fi module circuit is close to the ESP8266 chip, the circuit between the two DTIM Beacon intervals. According to the interval time of the router , the sleep time is decided. During the sleep, the chip can receive the interactive information from any server or mobile phone where the ESP8266 chip is always connected to the Wi-Fi. The router interval is generally 100ms-1000ms.

b) Light-Sleep: The power consumption is too lower when it is in this mode, which is similar to the Modem-sleep. Except from Wi-Fi circuit, ESP8266 also power powers off clock and immediately suspends the internal CPU. Which would be made as the less power than in Modem-sleep mode. c) Deep-Sleep: Automatically, the system cannot go into Deep-sleep. To enable the Deep-sleep mode the interface function system_deep_sleep is called by the users. The ESP8266 chip will be turn off Wi-Fi connectivity and data connection. The periodic wakeups are controlled by the working of the RTC module. G. Requirements Hardware and Software We are going to use two different modules such as lamp controller and a sensor board. The two modules needs Adafruit HUZZAH ESP8266 breakout, male jumper wires for the need of necessary connections and a breadboard. To measure the temperature and humidity, we use the DHT11 sensor with the sensor board. PowerSwitch Tail2 is used to attach a lamp in the lamp controller. Finally we need one FTDI friend board (USB cable) to program the ESP8266 breakout board. On the software side, we need the Arduino IDE install it including the ESP8266 package which is to be installed.

Then connect the two pins on the right on the GND pin of ESP8266 board and the +in pin to the pin number 5 of ESP8266. Finally the construction gets over by connecting the lamp or any electrical device to the PowerSwitch, the other end of the PowerSwitch is maintained with electricity.Refer Fig.4,
