The Secure, Automated Home

Project Team: Alec KulbackiProject Advisor: W. Thomas Miller

People expect more from of their possessions

Basic security systems have limited functionality

Creating a basic system then adding additional peripherals will appeal to consumers

Background:

There will be a wide range of peripherals.

The system will be complicated.

Must find a way to integrate every device.

Problem to be Addressed:

Design program to control all of the peripherals.

Run code on a laptop computer.

Utilize basic microcontroller to aid in communication.

Proposed Solution:

Primary: Design security system with home automation

functions Select devices to be used Establish a way for all devices to communicate

with the system. Secondary:

Allow devices to communicate wirelessly Add GSM connectivity to the system

Objectives:

Security:

Break in Detection

Hazard Detection

Keypad or Fingerprint Reader

Features:

Automation:

Home Tracking

Light Automation

Door Automation

Mobile Soundtrack

Burglary Detection

Primary security function

Hall effect sensors at windows and doors

Detect variations in electromagnetic field.

Hazard Detection

Smoke Detectors Traditionally Standalone

Smaller integrated circuit detectors. Can be linked to

microcontroller.

Arming / Disarming

Standard Keypad Easy to interface

Fingerprint Reader More difficult to store

image

SMS keyword from registered number

Home Tracking

Sensors placed at each door

Laser sensors Too expensive

Ultrasonic motion detectors Less expensive option

Light Automation

Will rely heavily on home tracking system

Will implement simple voltage divider with photoresistor in order to detect night/day.

Door Automation

Will be simulated

Small bidirectional motor will represent motorized door

Controlled using pulse width modulation

Mobile Soundtrack

Music will follow individual being tracked

Master sound system connected to multiple speakers

Transmission gates will toggle speakers on/off

Indirect Communication:

Computer will communicate with basic microcontroller

Microcontroller will also communicate with devices

Certain analysis may be done on microcontroller

GSM Module

Global System for Mobile Communication

Allows SMS communication

Costly

Wireless Communication:

Can be linked to devices for wireless communication

Can be connected via USB

Will increase price tag on project

Design of security system with additional functions Selecting components Evaluating their behavior Writing appropriate code to drive peripherals

Integration of all devices involved Indirectly connect devices to computer using

microcontroller or wireless devices
