ECE 5725 Final Project

There are a lot of valuable things during the design can be discussed: details of our components, reasons we choose specific parts, or improvement can be made in future, etc. They will be demonstrated below:

• • • There is one reason Sina Email Server is selected: Sina is guranteed to not require any verify code or multiple log in process, which can directly send out the email without being interrupted.

• • • There are two reasons we use a web server: Firstly, we have designed a memo function for our Intelligent Home Assistant system, but it is almost impossible for users to type in memo information throught the Pi TFT. Therefore we use a web part to deal with those problem. When users login into a website, they can easily type in what they want by their own computers or cellphones. Second, since the memo is part of personal privacy, we design an user management system that can not only guarantee the user information security, but also support a lot of users who use our own Home Assistant System. In addition, since the database collects a lot of data like temperature and humidity, then by some data analysis, we can make our control operation more intelligent in the future, like controlling the air conditioner remotely based on the temperature information.

• • • Spec of Our Web Server:
Ip Address: 47.254.19.144;    Configuration: 2 vCPU 4GB Ram;    OS: Ubuntu;    Server: apache-tomcat-7.0.90

• • • There are some reasons we used the touchscreen instead of GPIO buttons to change the alarm setting: Usually for a alarm setting, we have to change the settings for both hours and minuts by adding or substracting both two: which means we will need four buttons. However, if all four buttons are used, then we lose the ability to have any spare functions, for examole, emergent escaping button. Also, the buttons will not be as user-freindlt as a touchscreen, since the touch screen is much more straight forward, as shown below. Last but not the least, a touchscreen will be more fancy and mechanically reliable than a physical button.

• • • At first, we designed a really good UI with fancy effects like mouse hover effect, however, after we loaded it up to Pi TFT, it turned our that these fancy effects would actually lag the screen, and also, since we used our hands instead of mouse, these effects turned out to make no pratical difference. Therefore, we discarded these effects but focused on the most basic but clear one.

From above, it shows that our project can work perfectly in different modes as expected, and meets the budget requirement of less than 100 bucks. With our device, the users can easily control the components and get the information remotely. The home security part can provide users with relatively accurate data via email even when users are not around, while the web crawler can get the date and weather information as required then speak it out via a speaker. The web server can store data like memos of registered users, and can be ready for being captured by our system, while our UI can display all these things virtually through the Pi TFT.
In this project, we leveraged the knowledge from the labs and lectures we have down before, implemented bash scripts, Python codes or Java scripts to achieve some functions, demonstrated our ability to design UI with PyGame, interact with system and data through Pi TFT, GPIO buttons, web server, email server, speaker, etc. This project is not only a good chance for students to bridge the real world and embedded system with their own design, but also a good chance to show their understanding and passion to this course. Overall, we are really proud of our project.
