Team 16 – Efficient HVAC System Daniel Galarza – CpE Chung Chien Hsia – EE Marvin Martinez – CpE Kevin Ivy - EE

Motivation Household energy consumption Heating, Ventilation and Air Conditioning Different needs for different climates Humidity almost never considered

Project History iTemp – First design Did NOT work Efficient HVAC System – Second design Worked much better Expensive, and excessive components Stopped working later

Objectives Improve upon previous projects Make the project suitable for mass production

Specifications Reduce costs

The Database Will connect the control system hardware to the website in the Internet. Ensures the data on both systems are accurate and consistent. Updates any changes made on the data by either system. Implemented on a hosting website given by the sponsor.

Mobile Software Comparisons Android SDK is free Many different software programs available that supports Android Primary language is Java iOS SDK is $100 roughly Few other software programs are compatible with it Primary language is Objective-C

Main Block Diagram (first version)

Software/Services Used Hype – Used to design the site structure Dreamweaver – PHP and SQL editing Host Gator – hosting website provided by sponsor. Will host database for system. phpMyAdmin – Creates and edits SQLn databases

User Activity Diagram

The Website Allows a user to get access to their home HVAC system. Will closely follow the format of the control system. Will have all the same functionalities of the control system. Will obtain all of the consumer’s data from their specific entry within the database.
