Proposed Design
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.

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?
Analysis of Results
Requirements & Specifications
Problem Definition and Motivation
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!

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.

Surge Protection
This feature was not thoroughly tested due to the lack of hardware to

Cross Browser Compatibility
The 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
Prototyping
Conclusions
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.

Design Considerations/Methodology
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.
