Smart Security
Safety often tends to wary people in various part of the world. Whether or not an individual is living in a neighborhood with high or low crime rates, security have always been a main concern. With the rising crime rates, even in area known to be safe, security companies have been trying to attract customer with their competitive features, but not so attractive pricing. Often the price could range anywhere starting at $1,400 for installation and from $23 a month [1]. Our project is to provide a solution for people who want a home security system, but not have to pay the huge installation cost and monthly fee.
Abstract
Smart Security is a system targeted for home security that continuously monitors movement, when armed. This system will alert the user wirelessly when it detects motion via text message and flash LEDs on the spot to try and scare off the intruder. The whole process can be control using a web based GUI for arming and disarming the system.
Objectives & Introduction
The Smart Security project communicates with the user using wireless connection to alert them of any movement within the proximity of the sensor. A PIR motion sensor is, connected to a LPC1758 microcontroller board, used as a detector to register any movement. A Wifly module, also attached to the LPC, maintain wireless connection to send and receive commands. The user is able to communicate with the board using a web based GUI, designed with Bootstrap, to arm and disarm the system as he/she please. When armed and motion is detected, the board will send commands to alert user using text messages. To prevent spam, users will receive periodic text messages versus one per motion detected.
Our objectives for the project:
- Interface PIR Sensor with LPC1758 board and register readings
- Use Wifly to communicate between the board and server
- Send alerts in the form of email/text messages when movement is detected
- Setup alarm in the form of flashing LEDs
- Create an interactive user web interface that handles the control of the sensor
- Setup connection between the board and server

Parts List & Cost
Give a simple list of the cost of your project broken down by components. Do not write long stories here.
Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
Wifi Connection Issues
Many wifi connection issues were encountered. To solve this problem, a dedicated task was created to re-connect to wifi if the connection was ever lost.
Conclusion
Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
Project Video
Upload a video of your project and post the link here.
Project Source Code
Send me your zipped source code and I will upload this to SourceForge and link it for you.
