Automatic systems are being preferred over manual system. This unit talks about the basic definitions needed to understand the Project better and further defines the technical criteria to be implemented as a part of this project.Keywords-component; Automation, 8051 microcontroller, LDR,LED, ADC, Relays, LCD display, Sensors, Stepper motorI.NTRODUCTIONA home automation system integrates electrical devices in ahouse with each other. The techniques employed in home automation include those in building automation as well as the control of domestic activities, such as home entertainment systems, houseplant and yard watering, pet feeding, changing the ambiance scenes for different events (such as dinners or parties), and the use of domestic robots. Devices may be connected through a computer network to allow control by apersonal computer, and may allow remote access from the internet.Typically, a new home is outfitted for home automation during construction, due to the accessibility of the walls, outlets, and storage rooms, and the ability to make design changes specifically to accommodate certain technologies. Wireless systems are commonly installed when outfitting a pre-existing house, as they reduce wiring changes. These communicate through the existing power wiring, radio, or infrared signals with a central controller. Network sockets maybe installed in every room like AC power receptacles. Although automated homes of the future have been staple exhibits for Worlds Fairs and popular backgrounds in science fiction, complexity, competition between vendors, multiple ncompatible standards and the resulting expense have limited the penetration of home automation to homes of the wealthy or ambitious hobbyists.II.HOME AUTOMATIONHome/office automation is the control of any or all electrical devices in our home or office, whether we are there or away. Home/office automation is one of the most exciting developments in technology for the home that has come along in decades. There are hundreds of products available today that allow us control over the devices automatically, either by remote control; or even by voice command. Home automation (also called domotics) is the residential extension of building automation. It is automation of the home, housework or household activity. Home automation may include centralized control of lighting, HVAC (heating,ventilation and air conditioning), appliances, and other systems,to provide improved convenience, comfort, energy efficiency and security. Disabled can provide increased quality of life for persons who might otherwise require caregivers or institutional care. Earlier, we looked into the face of future when we talked about automated devices, which could do anything on instigation of a controller, but today it has become a reality.III.NEED OF AUTOMATIONWith advancement of technology things are becoming simpler and easier for us. Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscularrequirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily experience. Automatic systems are being preferred over manual ystem. Through this project we have tried to show automatic control of a house as a result of which power is saved to some extent.a) An automated device can replace good amount of human working force, moreover humans are more prone to errors and in intensive conditions the probability of error increases whereas, an automated device can work with diligence,versatility and with almost zero error.Replacing human operators in tasks that involve hard physical or monotonous work.Replacing humans in tasks done in dangerous environments (i.e. fire, space, volcanoes, nuclear facilities,underwater, etc)Performing tasks that are beyond human capabilities of size, weight, speed, endurance, etc.Economy improvement. Automation may improve in economy of enterprises, society or most of humankind. For example, when an enterprise that has invested in automation technology recovers its investment, or when a state or country increases its income due to automation like Germany or Japan in the 20th Century.b) This is why this project looks into construction and implementation of a system involving hardware to control a variety of electrical and electronics system.IV.SUPPY UNITA.Transformer:The main source of power(Fig 1) supply is a transformer. The maximum output power of power supply is dependent on maximum output power of transformer .We determine power from its current and voltage rating. e.g.: if there is a transformer of 12V, 500mA then maximum power delivered by transformer is 6Watt.It means we can drive a load from this transformer up to 6w. In our project our maximum power requirement is 1watt. So to provide this power we use 12V/250mA transformer. The maximum output power of this transformer is 4watt.it means it can easily drive load up to 4 watt.B.RectifierRectifier is a circuit which is used to convert ac to dc.Every electronic circuit requires a dc power supply for rectification. We have used four diodes.C.Input filter:After rectification we obtain dc supply from ac but it is not pure dc it may have some ac ripples .To reduce these ripples we use filters. It comprises of two filters low frequency ripple filter and high frequency ripple filter. To reduce low frequency ripples we use electrolytic capacitor. The voltage rating of capacitor must be double from incoming dc supply. It blocks dc and passes ripples to ground.D.RegulatorInitial stage of every electronic circuit is power supply system which provides required power to drive the whole system. The specification of power supply depends on the power requirement and this requirement is determined by its rating. The main components used in supply system are.Regulator is a device which provides constant output voltage with varying input voltage. There are two types of regulators (a) Fixed voltage regulator(b) Adjustable regulatorWe have used fixed voltage regulator LM78XX last two digits signify output voltage. The voltage for our system is 5V that is why we have used 7805 regulator which provides 5V from 12V dc.E.Output filter:It is used to filter out output ripple if any.F.Output indicationWe use LED to observe the functioning of our system. If he LED glows it confirms proper functioning of our supply.We have used four power supply units.This supply is for the microcontroller,display and relay unit.The microcontroller requires 5 volt supply to perform any desired task.G.Control UnitTwo control units were used one for internal system and one for external system and these control unit based on ATMELsAT89S52 microcontroller(Fig 2). The given capture shows the pins and basic requirement of microcontroller to make it functional. Detailed description of the controller is 100uf / 50v.In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software electable power saving modes. The Idle Mode stops the CPUwhile allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. Mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.The Downloadable Flash can be changed a single byte at a time and is accessible through the SPI serial interface. Holding RESET active forces the SPI bus into a serial programming interface and allows the program memory to be written to or read from unless Lock Bit 2 has been activated.H.FeaturesCompatible with MCS-51ProductsI.8KbytesofIn-SystemDownloadable Flash Memory ReprogrammableSPI Serial Interface for Program DownloadingEndurance: 1,000 Write/Erase Cycles4.0V to 5.5V Operating RangeFully Static Operation: 0 Hz to 33 MHz56 x 8 bit Internal RAM32 Programmable I/O LinesThree 16 bit Timer/CountersEight Interrupt SourcesUll Duplex UART Serial ChannelLow Power Idle and Power Down ModesI .Advantages Less power consumptionLow costLess space requiredHigh speedFig 2-Chip BoardAT89S52 is an ATMEL controller with the core of Intel MCS-51. It has same pin configuration as give above. The AT89S52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Downloadable Flash programmable and erasable read only memory and 2K bytes of EEPROM. The device is manufactured using Atmels high density nonvolatile memory technology and is compatible with the industry standard 80C51 instruction set and pin out. The on-chip Downloadable Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Downloadable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.The AT89S52 provides the following standard features: 8K bytes of Downloadable Flash, 2K bytes of EEPROM, 256 bytes of RAM, 32 I/O lines, programmable watchdog timer, two Data Pointers, three 16-bit timer/counters, a six-vectorJ .Pin DescriptionVCC: Supply voltage. GND: Ground., Port 0: Port 0 is an 8-bit open drain bidirectional I/O port. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as high impedance inputs. Port 0 can also be configured to be the multiplexed low-order address/data bus during accesses to external program and data memory. In this mode, P0 has internal pull-ups. Port 0 also receives the code bytes during Flash programming and outputs the code bytes during program verification. External pull-ups are required during program verification.Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 1 output buffers can sink/source four TTL inputs. When 1s are written to Port 1 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups.In addition, P1.0 and P1.1 can be configured to be the timer/counter 2 external count input (P1.0/T2) and the timer/counter 2 trigger input (P1.1/T2EX), respectively, as shown in the following table .Port 1 also receives the low-order address bytes during Flash programming and verification.Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 2 output buffers can sink/source four TTL inputs. When 1s are written to Port 2 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 2 pins that are externally being pulled low will source current (IIL) because of the internal pull-ups. Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that uses 16-bit addresses (MOVX DPTR). In this application, Port 2 uses strong internal pull-ups when emitting 1s. During accesses to external data memory that uses 8-bit addresses (MOVX RI), Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification. Port 3 Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. The Port 3 output buffers can sink/source four TTL inputs. When 1s are written to Port 3 pins, they are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current (IIL) because of the pull-ups. Port 3 receives some control signals for Flash programming and verification. Port 3 also serves the functions of various special features of the AT89S52.RST: Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device. This pin drives high for 98 oscillator periods after the Watchdog times out. The DISRTO bit in SFR AUXR (address 8EH) can be used to disable this feature. In the default state of bit DISRTO,the RESET HIGH out feature is enabled. ALE/PROG: Address Latch Enable (ALE) is an output pulse for latching the low byte of the address during accesses to external memory. This pin is also the program pulse input (PROG) during Flash programming. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency and may be used for external timing or clocking purposes. Note,however, that one ALE pulse is skipped during each access to external data memory.If desired, ALE operation can be disabled by setting bit 0 of SFR location 8EH. With the bit set, ALE is active only during a MOVX or MOVC instruction. Otherwise, the pin is weakly pulled high. Setting the ALE-disable bit has no effect if the microcontroller is in external execution mode.PSEN: Program Store Enable (PSEN) is the read strobe to external program memory. When the AT89S52 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory.EA/VPP: External Access Enable. EA must be strapped to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH. Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions.This pin also receives the 12-volt programming enable voltage (VPP) during Flash programming.XTAL1: Input to the inverting oscillator amplifier and input to the internal clock operating circuit.XTAL2: Output from the inverting oscillator amplifier.H. Display UnitFig 3-Display UnitLiquid crystal displays (LCD) is an alphanumeric display and widely used in recent years as compared to LEDs. This is due to the declining prices of LCD, the ability to display numbers, characters and graphics, incorporation of a refreshing controller into the LCD, their by relieving the CPU of the task of refreshing the LCD and also the ease of programming for characters and graphics. We have used JHD162A advanced version of HD44780 based LCDs.V.WHAT CAN BE AUTOMATEDA.Virtually anything in the home/office that is powered by electricity can be automated and/or controlled. We can control our electrical devices. The password is given with the help of controller and can be changed by simply making a small change in the program and then burning the program in the controller.B.Counter dependent automatic switching system of room After opening the lock when the person enters the room the counter gets incremented. Now if it is a day then the lights would not be switched on but if it is dark then the lights will automatically switch on. Now whatever may be the number of people entering the room the counter will automatically get incremented by itself and on leaving the room the counter will get decremented but the system will keep on working .Once the counter is zero in other words once everyone leaves the room the switching system will automatically stop working.C.Temperature controlled cooling systemOnce the person has entered the room he would not require to switch on anything everything will just happen automatically. Like if the temperature is high then the fan will switch on, on its own. Else it will remain in off state. This temperature is predefined by us in the controller. But this system will only work if there is a person in the room in other words if the counter is not zero.D.Light saving system This light saving system is used in two places for internal section and external section. If a person is not at home or sitting inside the room and it is dark outside then the lights will automatically get switched on and when its day the light will get switched off. This ensures power saving.Fire and Smoke sensorThis part detects any fire or smoke from a fire and set an alarm or an indication.VI. FEATURESPassword Based Locking SystemIn this system we have ensured a safe locking system. On seeing from outside the lock would not be visible but this inbuilt locking system ensures security. This lock can be opened and closed with the help of a password which we will give using a keypad. The door will only open or close only if the password is correct else it will remain in its original state. The lock cannot be broken because to the person standing Future of Automation: Future will be of Automation of all products. Each and every product will be smart devices that we use daily and that will be controlled through a smart chip called microcontrollers. Each and Every home appliances will be controlled either by PC or hand held devices like PDA or mobile handsets. Some examples of it are when you want you can switch on/off Fan of your home by mobile handset or PC.Smart Grid: Home automation technologies are viewed as integral additions to the Smart grid. The ability to control lighting, appliances, HVAC as well as Smart applications (load shedding, demand response, real-time power usage and price reporting) will become vital as Smart Grid initiatives are rolled out.VII. CONCLUSIONAn automated home can be a very simple grouping of controls, or it can be heavilyautomated where any appliance that is plugged into electrical power is remotelycontrolled. Costs mainly include equipment, components, furniture, and custom installation.Ongoing costs include electricity to run the control systems, maintenance costs for the control and networking systems, including troubleshooting, and eventual cost of upgrading as standards change. Increased complexity may also increase maintenance costs for networked devices.Learning to use a complex system effectively may take significant time and training.Control system security may be difficult and costly to maintain, especially if the control system extends beyond the home, for instance by wireless or by connection to the internet or other networks.基与单片机的智能家居系统与安全性摘要：随着技术的进步的东西变得更简单，更容易为我们服务。自动系统正在优于人工系统。本单元讲述，了解项目更好地所需的基本定义，并进一步定义了技术标准得以实施，因为这是项目的一部分。 关键词分量;自动化， 8051微控制器， LDR ， LED， ADC ，继电器，液晶显示器，传感器，步进电机1.引言家庭自动化系统的ahouse相互集成的电气设备。在家庭自动化中采用的技术包括那些在楼宇自动化，以及家务活动，如家庭娱乐系统，室内植物和庭院浇水，宠物饲养，改变气氛“场景”为不同的事件（如晚宴或派对）的控制，并使用国产机器人。设备可以通过计算机网络进行连接，以允许由a个人计算机进行控制，并且可以允许从internet.Typically远程访问，一个新的家庭是在施工期间配备用于家庭自动化，由于墙壁，插座，储藏室的可访问性，并进行设计更改专门以适应某些技术的能力。舾装一个预先存在的房子时，无线系统通常安装的，因为它们减少了接线的变化。这些通过现有的电源线，无线或红外信号与一个中央控制器通信。网络套接字可能安装在每一个房间一样交流电源插座。虽然未来的自动化家园已经主食展品为世界博览会和背景的科幻小说，复杂性，供应商，多个ncompatible标准和由此产生的费用之间的竞争家庭自动化的普及率已不限于富有或雄心勃勃的业余爱好者的家园受欢迎。2.家庭自动化家庭/办公自动化是在我们的家中或办公室的任何或所有电气设备的控制，我们是否有或离开。家庭/办公自动化是在技术的最令人振奋的发展为几十年来已经沿家之一。有数百种产品可今天，让我们自动地控制设备，或者通过远程控制;甚至通过语音命令。家庭自动化（也称为家庭自动化）是“楼宇自动化”住宅延伸。它是家庭，家务或家庭活动的自动化。家庭自动化包括集中控制灯光， HVAC（加热，通风和空调） ，家电和其他系统，以提供更好的便利性，舒适性，能源效率和安全性。残疾人士可以提供生活的谁否则可能需要护理人员或护理机构的人员增加质量。此前，我们看着面对未来，当我们谈到自动化设备，这可能会在控制器的控制下做任何事情，但今天它已经成为现实。3.自动化的需求 自动化的发展随着科技的进步的东西变得更简单。自动化是利用控制系统和信息技术，以降低生产商品和服务的需要为人类的工作。在工业化的范围内，自动化超出机械化的工序。而机械化提供了人工操作与机器，以协助他们工作 ，自动化大大减少了需要人的感官和精神的要求。自动化起着世界经济和日常经验越来越重要的作用。自动系统正在优于手动变体系。通过这个项目，我们试图表明自动控制的房子，结果能力控制在一定程度范围。 A一个自动化的设备可以代替人的工作力量好，而且人更容易出现错误和集约化条件下的错误的概率增大，而，一个自动化的设备可以与勤奋，多功能性和几乎为零的错误工作。在涉及重体力或单调的工作任务，取代人工操作。在危险的环境中完成的（即火，空间，火山爆发，核设施，水下等）的任务人类的更换执行范围以外的尺寸，重量，速度，耐力等人的能力的任务经济的改善。自动化可以提高企业，社会或大多数人类的经济。例如，当投资于自动化技术的企业回收投资，或者当一个国家或国家增加其收入由于自动化，如德国和日本在20世纪。B 这就是为什么这个项目看起来到建设实施，涉及硬件来控制各种电气和电子系统的系统。4.供给单位 A.变压器 电力的主要来源供给是一个变压器。电源的最大输出功率是依赖于变压器的最大输出功率。我们判断其电流和电压额定功率。例如：如果是有12V变压器， 500毫安然后通过变压器传送最大功率为6Watt 。这意味着我们可以从这个变压器了驱动负载，以6瓦特在我们的项目我们的最大功率的要求是1瓦特。因此，要提供这种力量，我们使用12V/250mA变压器。该变压器的最大输出功率为4watt.it意味着它可以轻松驱动加载到4瓦特。B.整流器 整流器是用来交流转换为直流的电路。每一个电子电路需要进行整改的直流电源。我们用四个二极管。C.Input过滤器：整流后得到的直流电源与交流，但它不是纯直流它可能有一些交流涟漪。为了减少这些波动，我们使用的过滤器。它包括两个过滤器，低频纹波滤波器和高频率的纹波过滤器。为了减少我们使用电解电容的低频纹波。电容器的额定电压必须是双从传入的直流电源。它会阻止直流和脉动传递到地面。D.调节器每个电子电路的初始阶段是电源系统，它提供所需的功率来驱动整个系统。电源的规格取决于功率的要求，这个要求是由它的等级决定的。在供电系统中使用的主要成分是。稳压器是一个装置，提供稳定的输出电压与不同的输入电压。有两种类型的稳压器（一）固定电压稳压器（二）可调稳压器 我们已经使用固定电压稳压器LM78XX最后两位数字表示输出电压。电压为我们的系统是5V ，这就是为什么我们使用7805稳压器，它由12V直流5V提供。E.Output过滤器：它是用来如有筛选出输出纹波。F.Output 指示我们使用的LED来观察我们系统的运作。如果他指示灯发出它证实了我们supply.We的正常运作已经使用了四种电源单元。这种供应是微控制器，显示器和继电器unit.The微控制器需要5伏的电源来执行任何所需的任务。 G.控制单元 两个控制单元中的一个用于内部系统和一个用于外部系统和基于ATMELsAT89S52微控制器（图2 ），这些控制单元。给出的截图显示的引脚和微控制器的基本要求，使之功能。控制器的详细描述是100UF / 50V 。此外， AT89S52设计与静态逻辑操作下降到零频率，并支持两种软件有候选资格的省电模式。在空闲模式下，CPU停止工作而RAM ，定时器/计数器，串行口和中断系统继续工作。模式保存RAM的内容，但冻结振荡器，禁止所有其他芯片功能，直到下一个中断或硬件复位。可下载的Flash可以改变一个字节的时间，是通过SPI串行接口访问。控股复位现役部队SPI总线为串行编程接口，允许程序存储器进行写入或除非锁定位2被激活阅读。H.发展前景 兼容MCS -51 产品I.8KbytesofIn - 系统可下载的闪存可重新编程程序下载SPI串行接口耐力：1,000写/擦除周期4.0V到5.5V工作范围全静态操作： 0 Hz至33 MHz的256 8位内部RAM32个可编程I / O线3个16位定时器/计数器八个中断源全双工UART串行通道低功耗空闲和掉电模式我。优势耗电量少成本低所需空间较少。高速芯片主板AT89S52是一个ATMEL控制器与英特尔的MCS -51的核心。它具有相同的引脚配置给上面。AT89S52是一种低功耗，高性能CMOS 8位单片机与8K字节的可下载的Flash可编程和可擦除只读存储器和2K字节的EEPROM 。该设备是采用Atmel的高密度非易失性存储器技术制造，与工业标准的80C51指令集兼容和引脚输出。片上可下载的Flash允许程序存储器通过一个SPI串行接口或通过传统的非易失性存储器编程器重新编程在系统。通过结合使用可下载的Flash集成在一个芯片上的一个多功能的8位CPU ， Atmel的AT89S52是一个功能强大的单片机，它提供了高度
