ESB 801

Background

•Incarnations of security systems have existed for centuries

•Each generation adds more security

•Modern systems are more advanced than ever

Modern Systems• Features:

• remote monitoring of home

• dialing owners/authorities

• (recently) smartphone integration

• Can require any of the following:

• costly installation by a professional

• monthly subscription fees

• a landline for calling

Original Problem Statement

•Develop a system to remove most requirements

•No professional installation required

•No subscription fees

•No landline required

•Implement smartphone integration

Overall Architecture

Final Project Status• Completed approximately 80% of original goals

• Major Time Alterations/Delays

• Raspberry Pi / TinyOS Installation

• Sensing Application

• Android Development

• Client/Server Communication

• Goals Abandoned

• Glass Break Sensor

• Non-local client/server communication

• Do have functioning security system

Raspberry Pi / TinyOS Installation

•ARM Processor!!!

•TinyOS - Open Source - Not developed for ARM

Sensing Application

•Interfaces with Telos B ADC

•Initializes antenna/radio transmitter

•Broadcasts sensor data

Android Development

•Android SDK

•Multithreaded Design:

•User Interface

•Background Process: TCP Client

2-Way Communication

•First attempt at server-client communication

•Sockets: local IP, Port

•Multiple input listeners: one for Android, one for sensors

•Texts via Google Voice API

Glass Break Sensor

•Abandoned Due to Time

•Focus was on getting working system

•Originally had goal to fabricate

•Learning Curve > Time Available

Non-Local Communication

•Opted for local-only message passing

•Budget/time constraints

•Not very practical

•Alternatives: 3rd party server or router configuration

Conclusions• Functioning Security System Strengths

• Is more informative than other Systems

• Gives User more control

• Instant Notification

• No Monthly Fee

• Low initial cost - (appx. $300)

• Weaknesses

• Only limited sensor options

• Detailed Set-up of Linux PC (not practical for production)
