Project Title
Abstract
We plan to make four nodes of Weather Clocks that can communicate with each other as well as access the real-time weather from the Internet. The clocks also measure the indoor Temperature and the Humidity. All this information is displayed on a user-interactive graphic LCD with touchscreen. Each node can access the information of every other node as requested by the user. And of course, they also display the time.
Objectives & Introduction
- The main objective is developing a custom wireless protocol using the Nordic Wireless Mesh Network that can be used for communication of the four nodes.
- We also plan to access the real time weather information from the internet. The user can input the location of the city, and our clock will fetch the data from the internet and display it. To implement this, we have decided to use the "Electric IMP". We are giving our clocks the IoT (Internet Of Things) functionality so we can access our clocks from virtually anywhere.
- To make the clocks interactive, we would be using a Graphic LCD with touchscreen(uLCD-32PTU from 4D systems) and design a beautiful GUI. The user can select what information he wishes to see by clicking the icons. The user can also access the information from the other three nodes. The LCD would be interfaced on UART.
- To measure the indoor temperature and humidity, we would be using the DHT-22 sensor which can measure both. It's a One-wire sensor which sends out the data in pulses when requested. Measuring the length or time period of these pulses tells us if the data is logic '1' or '0'.
- All weather information will be logged in the Flash memory and will also be displayed on the graphic LCD as a graph of the parameter v/s time when requested by the user.

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:
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?
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.
References
Acknowledgement
Any acknowledgement that you may wish to provide can be included here.
References Used
List any references used in project.
Appendix
You can list the references you used.
