This paper introdues the overall system arhiteture, disusses in detail the key tehnology of the ommuniation between MCU and the Internet. The purpose of system is to implement the remote wireless ommuniation between MCU and GPRS. The proposed projet aims in designing an automati operated system whih is apable of ontrolling the eletrial devies based on the sensors unit. This system reates a new era in the automation system. This system integrates human-mahine interfae. The ontrolling devie of the whole system is done using PIC Miroontroller. Whenever the sensors unit gets the input from respeted sensors like temperature LM35 sensor, level indiator sensor LM324 and Gas leakage detetor.these inputs are fed to the PIC miroontroller. The PIC Miroontroller performs appropriate task related to the data reeived like motor ON/OFF ontrol, fan as oolant ontrol system. The PIC miroontroller is also interfaed with GPRS module whih is used to display the devies monitoring status diretly to the predefined webpage. And we an also ontrol the devies using GPRS SMS servies. The PIC Miroontroller used in the projet is programmed using Embedded C language. Keywords: PIC ontroller; Wi-fi; Gprs; LCD display PROBLEM DEFINATION: An embedded system is a ombination of software and hardware to perform a dediated task. Some of the main devies used in embedded produts are Miroproessors and Miroontrollers. Miroproessors are ommonly referred to as general purpose proessors as they simply aept the inputs, proess it and give the output. In ontrast, a miroontroller not only aepts the data as inputs but also manipulates it, interfaes the data with various devies, ontrols the data and thus finally gives the result. The projet Design and Implementation of MCU and the Internet Communiation System Based on GPRS using PIC miroontroller is an exlusive projet whih is used to ontrol the robot using speeh reognition module and mobile phone. RELATED WORKS: Wireless tehnologies have been developing rapidly in these years. The obvious advantage of wireless transmission is a signifiant redution and simplifiation in wiring and harness [1]. Many ommuniation tehnologies, suh as IrDA, Bluetooth and ZigBee, GSM/GPRS (General Paket Radio Servie), et., have been developed for different situations. Nowadays, a kind of real time systems in whih multiple sensors onneted simultaneously to one gateway unit beome neessary, and they are transformed into wireless sensor networks (WSNs). In previous work, muh researh has been done using wireless sensor tehnologies. Literature searh indiates that appliations using wireless sensor tehnologies have already existed in the following four fields [2]: (1) Home automation and remote monitoring of houses. For example, Liang et al [3] developed a Available online: P a g e 1216

(2) Environmental monitoring, inluding humidity, temperature and radiation. For instane, Rosiek and Batlles [4] presented a system of dataaquisition from remote meteorologial stations using the mobile ommuniation networks (more speifially, GPRS). (3) Fault traking and fault management. For example, in [5], the authors developed an online diagnosis and real time warning system for vehiles using 3G tehnologies and GPRS ommuniations. (4) Health monitoring. For instane, Monton et al [6] designed an e-health approah to monitoring data of speifi population, suh as eletroenephalograms, eletroardiograms, eletromyograms and so on, whih uses ZigBee-based WSNs. ZigBee is partiularly suited for the implementation of a wide range of low ost, low power onsumption, reliable ontrol and real-time monitoring appliations within the smart home situations. The abovementioned four appliation areas are also losely related to the design of a WSN for smart homes. In the past, researh in smart home and inhome appliations was often limited to ZigBee tehnology, and gradually other long-distane network tehnologies suh as PSTN [3] and GSM [7] are adopted. It turns out that the use of these tehnologies makes information more aessible. This would signifiantly improve people s living quality. However, as a traditional wired network, PSTN has some problems, suh as unsatisfatory seurity assurane, inonveniene and high ost. Therefore we need a new solution. Among other hoies, the GPRS tehnology an solve these problems. Thanks to its unpreedented ubiquity, GPRS is now available almost anytime and anywhere, for anybody (being served). Furthermore, networks and the GPRS network onneting the ZigBee networks to the appliation server. Details about the design and implementation of the system are presented in the following setions. SYSTEM DESIGN: Miroontrollers: Cirumstanes that we find ourselves in today in the field of miroontrollers had their beginnings in the development of tehnology of integrated iruits. This development has made it possible to store hundreds of thousands of transistors into one hip. That was a prerequisite for prodution of miroproessors, and the first omputers were made by adding external peripherals suh as memory, input-output lines, timers and other. Further inreasing of the volume of the pakage resulted in reation of integrated iruits. These integrated iruits ontained both proessor and peripherals. That is how the first hip ontaining a miroomputer, or what would later be known as a miroontroller ame about.

Operation from split power supplies is also possible and the low power supply urrent drain is independent of the magnitude of the power supply voltage. Appliation areas inlude transduer amplifiers, DC gain bloks and all the onventional op amp iruits whih now an be more easily implemented in single power supply systems. For example, the LM124 series an be diretly operated off of the standard +5V power supply voltage whih is used in digital systems and will easily provide the required interfae eletronis without requiring the additional ±15Vpower supplies.thelm124lm124/lm224/lm324/lm29 02Low Power Quad Operational Amplifiers series are op amps whih operate with only a single power supply voltage, have true-differential inputs,and remain in the linear mode with an input ommon-mode voltage of 0 VDC. These amplifiers operate over a wide range of power supply voltage with little hange in performane Charateristis. At 25 C amplifier operation is possible down to a minimum supply voltage of 2.3 VDC. The pin outs of the pakage have been designed to simplify PC board layouts. Inverting inputs are adjaent to outputs for all of the amplifiers and the outputs have also been plaed at the orners of the pakage (pins 1, 7, 8, and 14).Preautions should be taken to insure that the power supply for the integrated iruit never beomes reversed in polarity or that the unit is not inadvertently installed bakwards in a test soket as an unlimited urrent surge through the resulting forward diode within the IC ould ause fusing of the internal ondutors and result in a destroyed unit. Large differential input voltages an be easily aommodated and, as input differential voltage protetion diodes are not needed, no large input urrents result from large differential input voltages. The differential input voltage may be larger than V+ without damaging the devie. Protetion should be provided to prevent the input voltages from going negative more than 0.3 VDC (at 25 C). An input lamp diode with a resistor to the IC input terminal an be used. LM 35: The LM35 sensor series are preision integrated-iruit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. To detet the heat produed during fire ourrene we use temperature sensor. The Temperature Sensor LM35 sensor series are preision integrated-iruit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature.

Avoid the noise of alohol, ooking fumes and igarette smoke. The sensitivity an be adjusted by the potentiometer. Relay: A relay is an eletrially operated swith. Many relays use an eletromagnet to operate a swithing mehanism, but other operating priniples are also used. Relays find appliations where it is neessary to ontrol a iruit by a lowpower signal, or where several iruits must be ontrolled by one signal. The first relays were used in long distane telegraph iruits, repeating the signal oming in from one iruit and retransmitting it to another. Relays found extensive use in telephone exhanges and early omputers to perform logial operations. GPRS Module : General paket radio servie (GPRS) is a paket oriented mobile data servie on the 2G and 3G ellular ommuniation systems global system for mobile ommuniations (GSM). The servie is available to users in over 200 ountries worldwide. GPRS was originally standardized by European Teleommuniations Standards Institute (ETSI) in response to the earlier CDPD and i-mode paket swithed ellular tehnologies. It is now maintained by the 3rd Generation Partnership Projet (3GPP). GPRS is a mobile telephony servie, whih simply put allows mobile phone users to onnet to the Internet using their phones. It was widely used, before mobile phones started beoming Wi-Fi enabled. It is very muh in the bakseat as of now, although it presents a viable alternative in emergenies, when other means of onneting to the Internet are not available. A type of relay that an handle the high power required to diretly drive an eletri motor is alled a ontator. Solid-state relays ontrol power iruits with no moving parts, instead using a semiondutor devie triggered by light to perform swithing. Relays with alibrated operating harateristis and sometimes multiple operating oils are used to protet eletrial iruits from overload or faults; in modern eletri power systems these funtions are performed by digital instruments still alled "protetion relays". The General Paket Radio Servie (GPRS) is a new servie that provides atual paket radio aess for Global System for Mobile Communiations (GSM) and Time-Division Multiple Aess (TDMA) users. It provides for the transmission of IP pakets over existing ellular networks, bringing the Internet to the mobile phone. Anything the Internet offers, from web browsing to hat and , will be available from GSM and TDMA servie providers via GPRSenabled devies. The main benefits of GPRS are that it reserves radio resoures only when there is data to Available online: P a g e 1219

The inreased funtionality of GPRS will derease the inremental ost to provide data servies, an ourrene that will, in turn, inrease the penetration of data servies among onsumer and business users. In addition, GPRS will allow improved quality of data servies as measured in terms of reliability, response time, and features supported. The unique appliations that will be developed with GPRS will appeal to a broad base of mobile subsribers and allow operators to differentiate their servies. These new servies will inrease apaity requirements on the radio and base-station subsystem resoures. One method GPRS uses to alleviate the apaity impats is sharing the same radio resoure among all mobile stations in a ell, providing effetive use of the sare resoures. In addition, new ore network elements will be deployed to support the inreased use of data servies more effiiently. Wi-Fi module ESP 8266 ESP 8266 is a Wi-Fi module that an be interfaed to miroontroller for wireless ommuniation. It has full TCP/IP protool stak. It aepts the ommands via serial interfae UART & then responds bak with the operations outome. It has high frequeny lok signal to drive its transmitter & reeiver whih is generated by internal & external osillators. It supports the speifiations of developed IEEE for wireless lan tehnology. It is design for 3.5V. easy to use & low ost LCD Bakground: One of the most ommon devies attahed to a miro ontroller is an LCD display. Some of the most ommon LCD s onneted to the many miroontrollers are 16x2 and 20x2 displays. This means 16 haraters per line by 2 lines and 20 haraters per line by 2 lines, respetively. transmission mode, module enapsulates the reeived data into TCP/UDP pakets and sends them to remote end. Furthermore, it an send the TCP/UDP pakets that ome from remote end to STM32W108. It ontains a protool head (8 Bytes) and data field (maximum is 256 Bytes). The EMSP protool onsists of 12 ommands to implement module ontrol, network ontrol and network ommuniation. SYSTEM IMPLENTATION AND PERFORMANCE EVALUATION : This projet is implemented using following software s: Express PCB for designing iruit PIC C ompiler - for ompilation part Proteus 7 (Embedded C) for simulation part PIC Compiler: PIC ompiler is software used where the mahine language ode is written and ompiled. After ompilation, the mahine soure ode is onverted into hex ode whih is to be dumped into the Available online: P a g e 1220

6 International Journal of Researh (IJR) e-issn: , p- ISSN: X Volume 2, Issue 12, Deember 2015 Available at miroontroller for further proessing. PIC ompiler also supports C language ode. It s important that you know C language for miroontroller whih is ommonly known as Embedded C. As we are going to use PIC Compiler, hene we also all it PIC C. The PCB, PCM, and PCH are separate ompilers. PCB is for 12-bit opodes, PCM is for 14-bitopodes, and PCH is for 16-bit opode PIC miroontrollers. Due to many similarities, all three ompilers are overed in this referene manual. Features and limitations that apply to only speifi miroontrollers are indiated within. These ompilers are speifially designed to meet the unique needs of the PIC miroontroller. This allows developers to quikly design appliations software in a more readable, high-level language. When ompared to a more traditional C ompiler, PCB, PCM, and PCH have some limitations. As an example of the limitations, funtion reursion is not allowed. This is due to the fat that the PIC has no stak to push variables onto, and also beause of the way the ompilers optimize the ode. The ompilers an effiiently implement normal C onstruts, input/output operations, and bit twiddling operations. All normal C data types are supported along with pointers to onstant arrays, fixed point deimal, and arrays of bits. PIC C is not muh different from a normal C program. If you know assembly, writing a C program is not a risis. In PIC, we will have a main funtion, in whih all your appliation speifi work will be defined. In ase of embedded C, you do not have any operating system running in there. So you have to make sure that your program or main file should never exit. This an be done with the help of simple while (1) or for (;;) loop as they are going to run infinitely.we have to add header file for ontroller you are using, otherwise you will not be able to aess registers related to peripherals. Proteus is software whih aepts only hex files. One the mahine ode is onverted into hex ode, that hex ode has to be dumped into the miroontroller and this is done by the Proteus. Proteus is a programmer whih itself ontains a miroontroller in it other than the one whih is to be programmed. This miroontroller has a program in it written in suh a way that it aepts the hex file from the pi ompiler and dumps this hex file into the miroontroller whih is to be programmed. As the Proteus programmer requires power supply to be operated, this power supply is given from the power supply iruit designed and onneted to the miroontroller in proteus. The program whih is to be dumped in to the miroontroller is edited in proteus and is ompiled and exeuted to hek any errors and hene after the suessful ompilation of the program the program is dumped in to the miroontroller using a dumper.

From the result of performane test it is observed that the performane and stability of wireless gateway suits the usual target of WSN appliation, whih is low real time demand, small amount of data transmission and low bandwidth. As WSN appliations expand further researh an fous on the low power design of wireless gateway, using wireless gateway ID to identify different deployment environments and adopting embedded Web Server tehnology enables users to visit different WSNs information.
