Powerpoint Templates Page Section 1 Introduction

Powerpoint Templates Page Introduction ●Smart Thermostat is a wireless thermostat with the capability of being controlled by a mobile application. ●It has the ability of being used in both residential and commercial settings. ●Controls all Heating, Ventilation, and Air Conditioning (HVAC) settings both manually and remotely ●Communicates with the mobile app via internet anywhere in the world

Powerpoint Templates Page Problem ●Most heating, ventilation, and air conditioning (HVAC) thermostats do not give users the ability of programming weekly schedules or complete wireless control via mobile application. ●Our market is for users that are frequently out of home or office and want to save money on monthly electricity cost by only heating or cooling the home when needed.

Powerpoint Templates Page Solution The Smart Thermostat will allow users to have complete control of the HVAC system at all times. [1]

Powerpoint Templates Page Solution Smart Thermostat will offer: [2][3]

Powerpoint Templates Page Section 2 Design Constraints

Powerpoint Templates Page Technical Constraints ConstraintDescription Internet Connection Must be able to receive and process controls from a mobile device over any internet accessible area. Temperature Range and Accuracy Must accurately adjust the temperature ±0.5°C over a range of 10°C (50°F) to 37.8°C (100°F) System VoltageMust operate at 24 VAC supplied from the HVAC system Weekly Scheduling Must be able to accept users’ weekly schedules and adjust HVAC settings accordingly. Mobile Control Must have a free mobile application that can be downloaded on a mobile smart device and control all functions of the HVAC system.

Powerpoint Templates Page Practical Constraints Economic The Smart Thermostat must: ●Not exceed cost to consumers of over $ ●Be desirable to the consumer by offering better abilities for less money than the competition Name Honeywell RET97E5D1005/U Wi-Fi Programmable Thermostat [4] CyberStat CY Wireless Internet Connected Programmable Thermostat [5] Price$119.00$79.99 ApplicationIOS or Android No mobile application Web application Schedule ability 7-Day programmable: 4 independent segments each day 7-Day programmable: 4 independent segments each day

Powerpoint Templates Page Practical Constraints Usability The Smart Thermostat will have a user-friendly mobile application. The app will be free of charge and will walk the consumer through setup. The app will be updated through the internet ● User will use the lastest version of Smart Thermostat’s app without extra fees

Powerpoint Templates Page Section 4 Testing

Powerpoint Templates Page Testing Procedure ●Test for temperature range and accuracy. Must measure accurately ±0.5°C from 10°C to 40°C ●Test for internet connection and mobile communication from various locations ●Test the weekly scheduling and manual override ability ●Test for constant power supply from the HVAC system to Smart Thermostat

Powerpoint Templates Page Potential Problems ●Failure to communicate at any distance where internet connection is avaliable ●Failure to maintain the weekly schedules down to the hour ●Failure to accurately operate the HVAC system at the desired temperature

Powerpoint Templates Page Section 6 Future Work

Powerpoint Templates Page Future Work ●Finalize PCB Design and test ●Finalize easy operable, wall-mounted component enclosure ●Enhance the android application ●Possible added Smart Thermostat features and capabilites
