EMA Smart Home

The EMA smart home system was the most complex group project I have worked on, requiring us to apply concepts and skills learned across multiple courses. Our team was awarded an “A” for the project.

Project Background

Given four BeagleBone Black Wireless boards and a selection of MikroBUS click modules, we were challenged to create a Wi-Fi connected system that supports sustainable living. Our solution was a smart home system that monitors energy usage in real time and intelligently controls devices to minimize consumption. To further extend its capabilities, we integrated an intrusion-detection node into the system.

Design Process

As a software-driven project, we focused on user interface design, prioritizing clarity, readability, and efficient communication of information. We also added Spline3D into the final design for more clarity. DEMO PAGE

Climate Node

The climate node monitors for temperature, humidity and the presence of humans, it toggles the fan on only when a person is detected and the environment is warm and humid

Bathroom Node

The bathroom node allows you to set a timer for how long you would want to shower for, using the buttons and display. It automatically starts when it detects you entering the shower. A buzzer is sounded when your time is up

Kitchen Node

The kitchen node monitors energy usage from the fridge and reports an energy score on the dashboard, It also functions as a fire alarm, the alarm sounds across all nodes if there is an uncontrolled fire detected.

Intrusion Node

The intrusion node detects for door knocks and the opening of the door at unusual times and starts an alarm across all nodes

Connectivity

Each board connects to a SocketIO web server which hosts the dashboard and coordinates events and alarms too.
