Home Security System

Question: Write a report about home security system. Answer: 1.0 Introduction In the modern technology, there are many methods and technology available for secure the home, bank, office, ATM etc. If the person went out means, this send alert message for a person where the fault is occurring. Nowadays theft rate is increased, so we are in the situation of secure the home. In our project a small credit card sized tiny computer called raspberry pi is used. It is used to teach the operation of computer language to the children. There are many microcontrollers available like ARM, AVR, Atmel and 8051.This microcontroller is the heart of the whole security system. Similarly so many sensors are used for identification of human body, fire, smoke and finger touch (James Adams, 2014). 1.1 Goal of the project Whenever we go away for job or anything, we have to secure our home and livings. Now everything should be wireless. Here GSM wireless technology is used to alert through message to the owner of home. This system is used to protect our valuables and also used as remote controlling system to our home. The buzzer used in this project may protect home before owner is coming because of the sound. We can also monitor the room temperature by smoke and fire sensor (Liz Upton, 2014). Here we are getting the input signal that may be an intruder, fire, smoke and users fingerprint. This input signals are processed in the Raspberry Pi chip. After the process, the output is display in the output system LCD. Buzzer can alert the user. 1.2 Overview of the project In this project, we are going to secure our home by using one small mobile phone. If the is away from home, he can secure his home from theft issue and some electrical problems like fire, smoke. In our project, Raspberry Pi 2 module B is used as a micro controller. This is heart of our whole project. All the modules which are used to secure the home are interfaced with GPIO pins of this Raspberry Pi. Here we are using the interfacing components are PIR sensor motion sensing, LDR sensor for light sensing, smoke sensor for smoke sensing and fire sensor for fire sensing. This interfacing board is fixed at home. The mobile of user is connected with home through GSM SIM900. If any problem will occur (intruder, fire, smoke or light), this GSM is transferred the message alert to the user when the person doesnt stay at home. Hence the can secure his home by himself or with the help of police station (Weaver, 2006). 1.3 Literature review Home security system using microcontroller 8051 In this project microcontroller is act as central processing unit for the whole security system. IR transmitter and receiver are used for data transmission.IR transmitter is fixed at the home where we have to monitor. IR receiver is fixed at controlling place. If the any changes in temperature or smoke or whatever we need to monitor, that signals are captured by the IR transmitter and processed by the microcontroller. Then the signals are sent to the receiver end. If there is any change, buzzer will start to beep. LCD shows the message. Using max 232 IC, the whole is interfaced with PC. Hence using that PC the owner can monitor and secure his home and other properties (Philip Walker, 1985). Home security system using arduino Here the security system is used arduino UNO microcontroller to process the input and output. 12V dc supply or battery is used for power supply. Similarly if there is any motion or fire, etc, those sensor can detect the changes which are according to the connected sensors. If those collected input signals are above the threshold level, the sms alert is transferred to concerned mobile number of the user depends on the preprogrammed warning messages. For this, GSM is used for wireless technology (Philip Walker, 1985). Microcontroller is a single microcontroller which needs to connect the other peripherals . But the arduino is a developed board which contains the series of microcontrollers. It is a platform having Atmel AVR microcontroller and peripherals. We can run this arduino with minimum circuitry and support the high level language. So when compared to microcontroller and arduino, arduino is the better choice for electronics project. But we can choose the arduino for simple projects like closing opening the gate and home automation. Whenever we need the full fledged computer, we can choose the Raspberry pi module. To drive the complicated robot and to perform the multiple tasks like industry applications and military applications, selection of Raspberry pi is the better choice. And also some home security system has been developed using Bluetooth. Among the all wireless technology, GSM SIM900 is the wide range technology which can be suitable for all real time applications (James Adams, 2014). Importance of the project The main goal of this project is to secure house. Whenever we go out, we need to protect our home in safety manner. Using this project, we can achieve our goal. Any product is to be cost effective, compact and easy to use. That is very important. Raspberry Pi 2module B which is used in this project is having very low cost. If we use this concept in big industries, group of Raspberry Pi can act as a server. For that type of application, we can do at low cost by this Raspberry Pi. And also Raspberry Pi 2 module B is very small in size. It credit card size minicomputer that doing all the process that computer can. It also support hobbyist, commercial and industrial project. So Raspberry Pi is the outstanding product. Because of using RPI, our whole project is also become very effective. And also the so many sensors are used to protect home from fire and light. The advantage of this system is giving privacy on both sides because it is monitoring by one person. All the components connecte d with RPI are having the capability of communicating through GSM. GSM is the software used for data transmission to the output end. The system is digital and fully customized(Philip Walker,1985). 2.0 Brief overview of the project Home security system is a revolutionary concept that is used to secure our house and valuables. In this paper we are introducing a new technology is Raspberry PI. Raspberry PI will act as a single board computer. This concept is also used in small, medium and large scale industries and also in military security applications (Liz Upton, 2014). Figure: overview of the project 3.0 Conclusion Home security system is a fast upcoming system with different technologies used in this world. The home security system using Raspberry Pi is the effective project which can be used not only for house also for business. Because of using RPI, this project suits for all type of security system at low cost. Hence one person can assure that to secure their properties by using a single cell phone. In this project, the sensors are interfaced with UART port of Raspberry pi2 module B which can be send the information like motion, light, smoke and fire. Also the print module is used for allow an authorized persons only. Raspberry pi2 module B PI camera is used here to capture the image of unauthorized person and Wireless GSM technology has sent the information to alert the home owner(KasimogluAkyildiz, 2004). Hence the home security system using Raspberry pi2 module B has been developed. 4.0 Future Development The future scope of this project is reducing time and resources. Raspberry pi is not suitable for all type of applications. So in future we can implement with Arduino processor and also added remote access for electronic equipments with this project. For future development, we can use image processing concept with home security system. That is we have to fix face recognition module at the home entrance or door. Here home owners face is used as a passkey to open and lock the door. Now every person has the smart phone. We can use this as remote to access the home appliances. This will be an efficient and most secured security system for home, ATM, bank. And we can passes a signal to the police station by GSM, Thus one can protect more their valuables. Also we can implement this security system for military applications. This can be avoid the terrorists or other unauthorized persons (FriedhelmHillebrand, 2001). 5.0 References AnanthaChandrakasan AmitSinha.(2001).Dynamic Power Management in wireless Sensor Networks.IEE Design Test of Computers (Vol.18).
