Mobile Phone Based Environment Control/Security System Christopher Carroll B.E. Electronic and Computer Engineering

Overview Project brief System overview Progress to date Remaining tasks

Project Brief In this project, the student will be required to design a system which will allow the user to control environmental switches (e.g. heat, light etc.) and/or security functions in the home from a standard mobile phone handset. A number of wireless technologies are available on most standard phones (including SMS/Data, Bluetooth, WiFi) which could possibly be used as the access channel.

Gumstix Microcontroller System Overview Mobile Phone Controlled Device SMS Device Contact Carer Everything OK? no

Progress to date Background research, analysis of similar systems and identification of hardware and software components to be used Developed a Java phone application and tested on emulator Set up a client / server Bluetooth connection between two mobile phones

Remaining Tasks Set up Bluetooth connection between Gumstix and mobile phone Interface Infrared LED to Gumstix device Write C or C++ program to convert Bluetooth to Infrared signal Control of external devices such as lights, radio and television Modify system to also include the use of SMS to communicate with elderly/disabled user to assess situation. Automatically contact carer if help required

Conclusion Have greatly improved programming skills such as Java and C Conversion between Bluetooth and Infrared is a welcoming challenge Aim to build a working prototype that can be used by someone in Enable Ireland
