Project Title

Automated Meeting Room Reservation

Abstract

To implement a wireless automated meeting room reservation system using Nordic Wireless modules and SJONE boards. Each SJOne board will communicate with a central Board to convey the status of meeting room in use through.

Objectives & Introduction

The automated meeting room reservation is achieved through the built-in Nordic Wireless interface. Each board acts as a node in the mesh network which sends and receives information and communicates with a central node. The following objectives are to be implemented:

• Auto detection of room use
• Shortest Path routes
• Address nodes with auto-replies
• Track the rooms in use at the central server.

Schedule

Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Parts List & Cost

Design & Implementation

System Overview

Overall System Diagram

The design and implementation of the project has been divided into sections pertaining to hardware and software design as given below:

Hardware Design

PIR Motion Sensor

PIR Motion Sensor plays the primary role of detecting motion in the vicinity, in this case,a room. It relies on heat changes in the environment by using temperature variations as an indicator. The sensor has 3 pins: Vcc, GND and a GPIO which can be used while interfacing with a micro-controller. Detection takes place in conical area(~120 degrees) in front of the sensor and the range is approximately 30 feet. This device is power compatible with 3.3V/500uA and 5V/800uA as well and will be interfaced with each of the SJ-One boards that are being used in this project.

PIR Motion Sensor

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:

My Issue #1

Discuss the issue and resolution.

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?
