Proposed Design

The most basic UI requirement was to keep it simple. Because the target population is home, apartment or boat owners, anyone that can use an alarm on their smartphone should be able to use the application.

For this project, we used as much open source software and hardware platforms to minimize the amount of work and enable the project to be completed in a timely fashion.

Design Considerations/Methodology

Every year, consumers worldwide lose over 15 BILLION DOLLARS to vampire power consumption. Vampire power or, standby power, refers to the power consumed by electrical devices while they are turned off, or are in standby mode. Yes, even after you turn a device off it can still cost you money!

Have you ever been ironing your shirt before work, already ten minutes late to a meeting that could determine the future of your career? If you have, or have been in a similar situation, it is very likely that you forgot to turn off the iron or some other hazardous appliance. Cue gut wrenching feeling in your stomach 30 miles from home and already late for work. Wouldn’t it be nice if you could reach into your pocket and effectively unplug that iron from anywhere in the world?

Intellibar is an intelligent power strip that allows YOU to take control of your electrical devices ANYTIME from ANYWHERE. •The power strip is composed of four outlets to allow for multiple device connection. •Through the use of wireless WIFI communication and a user-friendly web application, the power consumption of each outlet can be remotely monitored. Historical data of each outlet’s power consumption is also a click away on the web application. •Users are able to remotely switch each outlet on or off with the touch of a button. •Intellibar provides you peace of mind with built in surge protection that will protect your electrical devices from dangerous power surges.

CURRENT STATE OF THE PRODUCT

Currently, the first IntelliBar prototype is meeting more than 2/3 of the design requirements. The web application is functional, user friendly and rivals similar products on the market in terms of compatibility, storage, usability and appearance. The response time of the software is exceeding standards, but the latency in data acquisition is an issue. The remote switching of the outlets works seamlessly. The power consumption circuitry for the prototype is not functioning as efficiently as during initial testing and currently is not reliable. The enclosure of the product is practical and functional, but the durability of the material is in question. Additionally, the prototype enclosure does not meet requirement standards in appearance or safety. The surge protection of the product is installed, but testing has not been done to ensure reliability.

In terms of current marketability, if no further modifications were made, we do believe the first IntelliBar prototype would be marketable as a broad range, wireless, remote controlled, power strip. Its ability to wirelessly control its individual outlets from any WiFi compatible device via the web application is a desirable function in itself.

Parameter Test

Surge ProtectionThis feature was not thoroughly tested due to the lack of hardware to generate

the required testing voltage

Cross Browser CompatibilityThe application was run on all major browsers including mobile versions to ensure that all the design features were consistent and functionality was

maintained

Data Acquisition The data acquisition and measurements were compared to an existing product that

measured the parameters that we were seeking to also measure

Latency This was tested in different areas with different WiFi connections

Simulation of the hardware was done in PSpice to ensure the circuit that was designed would function as it should and properly integrate with the other hardware components.

We would like to thank our faculty advisor, Dr. Sanjukta Bhanja, for providing the necessary resources and advice that helped in making this project a success.
