Design And Implementation Of Arduino Based Bluetooth Control Sliding Door

ABSTRACT

Security is becoming an important issue everywhere nowadays. Every person wants  his house, factory; bank etc to be secured. house security is becoming necessary as the possibilities of intrusion are increasing day by day. In this paper, door security system has been designed that has a unique feature . Arduino was used, which is considered one of the modern programmable device and we also used HC-05 wireless Bluetooth transceiver so as to control door Here, our application uses Arduino as it’s controller and HC-05 as a communication link between mobile application which we developed using MIT app inventor 2. This paper aims to develop a door security system using LDR sensor & Ultrasonic sensor,servo motor ,laser module, data from all these sensors is continuously received and processed by Arduino UNO board which act as micro controller unit., a LDR sensor measures intensity of a particular place, while ultrasonic sensor works to measure distance by sending small pulse .The Bluetooth module HC-05 is used to control the door through the application DOOR developed by us ,thus the system ensures  home safety as well as security.

1. INTRODUCTION

In day to day life home security is very important factor. It is trending issue in 21st century. Security is primary concern everywhere and for everyone. every person wants his home, industry, banks etc to be secured. This project describes a security system that can control home door. This is a useful and simple security system.

here, our application uses Arduino as it’s controller and detects whether the door is unlocked or locked using ultrasonic sensor & LDR values.the Ultrasonic sensor measures the distance of door and LDR detects the intensity of laser light falling on it and based on it decides if its locked or unlocked. This paper is based on embedded system where micro controller is use for home security. This system can operate using cellular phone with the help of Application that we developed. This system is to implement micro controller based controlled module that receives it’s instruction and command for  cellular phone over Bluetooth. This micro controller then will carry out the issued Commands and then communicate the status given applicants or device back to the smart phones.

II.            LITERATURE REVIEW

As per survey there exists many such systems that could control door. Each system has its own unique feature. Following model describes the work performed in project. Arduino UNO itself act as a micro controller. Design and implementation of low, smart and real-time monitoring and controlling of door security using Arduino.Arduino along with HC-05 and mobile Applications allows us to control door from any where in the home and constantly keep watch on it. Some system provide security alarm using low processor chip. R-Pi would exchange data or would communicate with the help of Bluetooth, Wi-Fi and Ethernet. These systems have their own disadvantages. For example, system- implementing must requires Wifi/Ethernet  for the data communication. These system also proficient for home automation.

 Bluetooth Specifications : Bluetooth is a global specification for a small form-factor, low cost radio solution providing links between mobile computers, mobile phones, and other portable handheld devices, as well as connectivity to the Internet. The Institute of Electrical and Electronics Engineers (IEEE) has given the IEEE

802.15 standard. Its main strength is its ability to simultaneously handle both data and voice transmissions. A Bluetooth is capable of supporting asynchronous data link with each client and Also synchronous voice links with up to three client devices. It provides range of up to 10m at transmit power of 1 mwatt. The range can be extended to 100m if the transmit power is increased to 100 m watt. Bluetooth has a data rate of 1 Mbps. Bluetooth is a standard for a small (9mm x 9mm) , cheap radio chip to be plugged into computers, printers, mobile phones, etc. A Bluetooth takes the information normally carried using the cable, and transmits it at a different frequency to a receiver. Bluetooth, which then will give the information received to the computer, phone or whatever. Bluetooth offers most economical solution for low to medium- speed device connectivity. It aims at low power consumption and also provides security for mobile devices. The basic function is to provide standard wireless technology so as to replace the multitude of propriety cables currently linking computing devices. [2]

Working of Bluetooth : A Bluetooth module is a short range device of around 10 meters which provides both sound and data transmission. The Bluetooth device uses an IEEE 802 standards wherein the connections can be point-topoint or point-to-multipoint. The data transfer rate is 3mbps and the maximum range of a Bluetooth device can be 10-100 meters. The default baud rate is 38400 and also other supported baud rates are   9600,   19200,57600,115200,230400  and

460800. Bluetooth can connect up to 8 devices
