PROBLEM STATEMENT
RESULTS
• The Energy Management and Monitoring System consist of the design and
• The system tracks the energy consumption of a household.
implementation of a system that is capable of measuring real time power
consumption in a single phase residential home or business.
• It has a user friendly LCD display, it also stores data in a SD card.
• The objective of the product is to allow the user to keep track of the energy
used every day at home, the cost of this energy and to take control over circuit
branches.
• The collected data is shown in a web page. This way the end user has
access to the real time information.
• The system has the capability of turning ON/OFF different circuit
branches.
• This system has been designed assuming that it will operate at indoor
environment and has just a few limitations such as it is not aimed to improve
the efficiency of the energy usage.
• Configurable SMS alerts when maximum consumption limit has been
reached.
• The final product has very low chances of causing accidents or having
malfunctions and the components are easy to replace.
• The system is considered to have minimal environmental impact. The
materials and components used are considered sustainable, making this
product extremely environmental and safe
OBJECTIVES
Ease to use
• User friendly display.
• Easy to install product.
• Account registration and online user profile.
• User friendly Energy Audits.
• The user can save energy and money. It also alerts the user when a
consumption limit is reached.
CONCEPT
Marketability
• Autonomous system with minimal maintenance requirements.
• Low production cost.
• Precise and reliable.
• Safe and easy installation
• This system is conformed by current and voltage sensors, a LCD display, SD
card, router and an Arduino microcontroller.
• The microcontroller drives a relay card which will turn ON/OFF designated
circuit branches through Internet.
Functionality
• Allows accurate analysis of energy consumption.
• Remote control over designated circuits branches.
• Configurable alerts.
• Displays data on LCD screen and web site (Real time online monitor).
• It uses three sensors to get the current and voltage values, these values are
processed by the microcontroller to calculate power, rate, power factor,
energy consumption and energy cost.
• All the data is uploaded to an online server and interactive graphs are
generated and embedded in the application main website.

• Through this project we learned new ways to approach real
engineering problems.
• The final product has a high potential of getting to the market because
it helps improve people’s life and economy. It also helps the planet.
• Society will benefit from this product because it is a tool to keep track
of the energy consumed, and it provides a platform to control outlets and
utilities.
• This project represented a challenge for us as students, but a great
experience for our future career as engineers.
