Smart Homes Poster

Home automation systems are attractive due to their ability to control and monitor a home, even from remote locations easily and comfortably. Additionally, home automation systems can be used to minimize energy consumption. One of the largest energy consuming sectors in America are buildings (residential and industrial). They account for about 39% of total U.S energy consumption as published by the U.S. Energy Information Administration [2]. Home automation uses technology capable of monitoring and controlling many functional parts of the house including heat and ventilating systems, lighting, irrigation, etc. This is done automatically saving time and resources, reducing human effort, and overall making the life of people more convenient and flexible in many tangible ways.

This project aims to reduce energy consumption of home lighting while also allowing wireless and remote control of lights throughout a home using the low cost and powerful ESP32 development board. By tracking the presence of the user, the system can turn on/off lights depending on the user’s travel through the home. This project focuses on the potential of providing great flexibility to homeowners with the advantage of allowing them the operation of the system remotely. Localizing the control board on a single device promotes convenience and practicality —a massive improvement for technology and home management. A substantial aspect behind the design of this project is the better usage of energy. An average household dedicates 11% of itsenergy budget to lighting [3]. Implementing a smart light control system such as the system proposed in this project reduces the cost of energy consumption while simultaneously provides ease of use and flexibility.
