GEOFENCE

MISSION

  • Design an Android App that is capable of connecting to smart devices through Wi-Fi and APIs.
  • Make everyday life less tedious for our users through the ability to control smart devices, schedule tasks, utilize cameras, and monitor smart sensors.
  • Our app is engineered for user satisfaction, with a UI designed for easy to understand navigation and minimal button presses.

DEVICE CONTROL

SYSTEM ARCHITECTURE

  • Connects to the app via Google Play Services
  • Requires permission from the user to have access to background location
  • User sets a location and a radius
  • Transition functions to activate Smart Devices

FUTURE WORK

MOTION DETECTION

  • Connection and control over several smart devices including smart plugs, lights, cameras, and sensors
  • LIFX Smart Light: Power, brightness, color Control via API connection and custom commands
  • Shelly Smart plug: Power control via HTTP commands over LAN connection
  • Switchbot thermo-hygrometer: Connects via Switchbot API and provides temperature and humidity data over the internet via request
  • RaspberryPi camera with flask server for virtual motion detection monitoring
  • RaspberryPi Camera Connects to the app via Flask server
  • Motion detection script written in Python
  • Frame Differencing
  • Motion detection can be used to trigger Smart Devices
  • Integration with Amazon Alexa/Google Home
  • Feedback System for water/electricity usage
  • Integration with machine learning to automatically detect users’ schedules
  • Integration with Matter/MQTT Protocols

SCHEDULING

SECURE BACKEND

  • Set timers for all connected smart devices
  • Choose specific days and times for automated actions
  • Device-specific options (color/brightness for lights)
  • Receive notifications when scheduled actions occur
  • Flask app hosted on AWS EC2 Using HTTPS
  • User authentication with PBKDF2-SHA256 hashing and salting
  • Time-limited verification codes for email and password resets
  • SQL injection protection via parameterized queries

UI

  • Grid layout allowing selection between device types
  • On/Off toggle buttons for each device on home screen
  • More functionalities when selecting specific device
  • Dynamic icons reflecting device connectivity on home screen
  • Ability to add device, access settings, and schedule tasks on the same page
