3. Problem Statement –The need for integrated sensors –Detects gas, smoke, and home invasion (burglar alarm ) –Web-Based platform –Pre-defined Actions

4. Background Wireless Fire Alarm System (University of Connecticut) Portable Gas Sensor (Iowa State University) Speech Synthesized Temperature Sensor (University of Illinois)

5. Objectives This system should activate an alarm This system should be accessible The device should be useful The system should be Marketable The system should be valuable Monitored status should be accessible remotely, private, user friendly

6. Intended Users and Uses UsersUsers –Computer Literate UsesUses –monitor the status of gas and smoke concentrations, and intrusion

7. Needs / Feasibility Analysis Needs AnalysisNeeds Analysis –Question 1: Why is there a problem with sensors locating a specific threat? –Question 2: Why does the threat have to be located specifically if the alarm alerts the user with sound? –Question 3: Why is there a need to have three separate sensors for one system instead of integrating them into one? –Question 4: Why is there a need for web-based monitoring when some systems can be monitored using a LCD panel? –Question 5: Why is there a need for the system to control functions in the home to eliminate certain threats?

8. Feasibility Analysis

9. Concept Development The pros and cons of selections Advantages: –Power –Wireless –Serial –Individual connections Disadvantages: –Wired systems may be more costly –Cumbersome –Constant battery replacement –Signal interferance –Serial Signal Delays

10. Standards ISO 7240-1 –connected to control and indicating equipment AS/NZS 4379.2:1996 –the remote database access client, when database language used is SQL ITS-90 –t90 / °C = T90/K - 273.15

11. Ethical Considerations DilemmaDilemma –unauthorized access to private information –security risk from altered information StakeholdersStakeholders –The stakeholders involved in this project will be the owner or other users of the security system, hackers, and the general public. Determining the optionsDetermining the options –Best extreme –Worst extreme –Compromise Application of Ethical TheoriesApplication of Ethical Theories –Ethical egoism –Utilitarianism –Ethics of care
