WEEK 8

Title : Research and Findings ( Bluetooth classification and security)

BLUETOOTH RANGE

-There are three classes in Bluetooth which depends on the power that it needs to broadcast. The exact range of the Bluetooth broadcast depends on the surroundings.

Class 1 – 100 meters range with maximum permitted power set at 5mW.

Class 2 – 10 meters range with maximum permitted power set at 2.5mW.

Class 3 – 1 meter range with maximum permitted power set at 1mW.

BLUETOOTH SECURITY

-Security is important when communicating without wires. If your device is discover able, anyone in the vicinity can do a device discovery and find your Bluetooth device. They may determine which services your device is offering and try to connect to them. Another problem is eavesdropping, which can be done very easily when communicating without wires.

-In order to handle these threats, the Bluetooth specification defines a security model based on three components:

• ·         Authentication
• ·         encryption
• ·         authorization

-In addition, three security modes are defined, enforcing different levels of security. A security manager is used to handle the security transactions in the Bluetooth system.

WEEK 7

Title : Redraw a block diagram

Doing some more research from the previous block diagram to identify the input, process and the output from the project. Helping from the supervisor is also included in making of the process.

PROBLEM SOLVING

Work and problem encountered :

-Supervisor gave some recommendation and suggestion to give some improvement for this block diagram. Therefore, I need to do more research on how reliable of this project to the society. Reliable means how far this project can overcome the problem of hackers out there that try to hack the coding system.

WEEK 7

Title :Research and findings

-Doing a research and list the requirement needed to meet the objectives.

- After making some research on the internet and guidance from the supervisor, I managed to get an idea, technique, and method to imagine my project flow. The first requirement needed to run the project is to identify the components. The componentsare :

•        Bluetooth Module
•       PIC
•       Relay
•      Solenoid
•    Motor
•     LED lamp

   The listed components below are just some illustrated images idea taking from the websites.

WEEK 6

 Bluetooth Module (HC-05)

Bluetooth serial module is used for converting serial port to Bluetooth. These modules have two modes: master and slaver device. The device named after even number is defined to be master or slaver when out of factory and can’t be changed to the other mode. But for the device named after odd number, users can set the work mode (master or slaver) of the device by AT commands.

When HC-05 is out of factory, one part of parameters is set for activating the device. The work mode is not set, since user can set the mode of HC-05 as they want.

The main function of Bluetooth serial module is replacing the serial port line, such as:

1.      There are two MCUs want to communicate with each other. One connects to Bluetooth master device while the other one connects to slave device. Their connection can be built once the pair is made. This Bluetooth connection is equivalently liked to a serial port line connection including RXD, TXD signals and they can use the Bluetooth serial module to communicate with each other.

2.      When MCU has Bluetooth slave module, it can communicate with Bluetooth adapter of computers and smart phones. Then there is a virtual communicable serial port line between MCU and computer or smart phone.

3.      The Bluetooth devices in the market mostly are slave devices, such as Bluetooth printer, Bluetooth GPS. So, we can use master module to make pair and communicate with them. Bluetooth Serial module’s operation doesn’t need drive, and can communicate with the other Bluetooth device which has the serial.

But communication between two Bluetooth modules requires at least two conditions:

Ø  The communication must be between master and slave.

Ø  The password must be correct.

WEEK 6

BLOCK DIAGRAM OF PROJECT 

This project consist with smartphone as a tool or remove to turn on the solenoid for open the door or gate and to turn on motor and led lamp. First of all turn on the bluetooth of smartphone and paring with some bluetooth device of project. After that send information or some code to start the operation of output by pic circuit will process and simulate the data and trigger relay to start the operation of ouput

WEEK 5

FLOW CHART

For this week, i had meet with advisor to discuss about my project flow chart. Madam Hidayah was give some idea how to make flow chart according from the introduction that i propose at week 4. First of all i have done some flow chart before meet with Madam Hidayah and my flow chart is at the figure above. After discussion with my advisor, Madam Hidayah was advise me to make flow chart focus more to my project title and the result of my flow chart after discuss with my advisor at the figure below:

This is my flow chart after discussion, you can see that the flow chart is focus more to the title of project which  is "Development of Accessible Remote-Control for Automation Level Crossing Gate"

WEEK 4

INTRODUCTION ABOUT PROJECT

Due to the advances in Smartphone features and its low cost, the Smartphone has become one of the most commonly used in handheld devices. Smartphone of nowadays offer many features and applications. However many of the applications are only for entertainment purpose. Due to the popularity of Smartphone and the features they offer, these devices can be used in many other ways.

            One way is developing the Android application for Smartphone to control the operation of accessible sensing system using Bluetooth. When discus about security is very important nowadays and it will be more helpful if this feature can be added in the Smartphone to access and control the system at our property. It will provide a new concept and idea to the Smartphone application developers. Considering these factors this project decided to implement the Android application in Smartphone for “"Development of Accessible Remote-Control for Automation Level Crossing Gate"

           "Development of Accessible Remote-Control for Automation Level Crossing Gate" will allow user to access their property by Smartphone using Bluetooth and with this application also user can control the lighting and fan system in their property. This project will increase the security system and make life become easier to user because of the technological developments.
