  1. Team 7: Sunoco HotdogEye HomeMid-Semester Presentation Hong, Keetaek Baek, Jinwook Lee, David

  2. Concept and Motivation • Concept: This project will inform the individual in case of fire or break-in at the house through mobile text messaging • Motivation: Anything can happen at home whether it is vacant or no adult is present. This prototype provides a cost efficient way to inform the home owner in case of a troubled situation at home

  3. Status Update • Accomplishments • Wrote a program that can send text messages • Registered for propriety SMS server site • Conflict in voltage input for smoke sensor • Mitigation • Sensor Compatibility – voltage adaptor • Assumption • We will be able to integrate breadboard into Tmote in future development

  4. Eye Candy Mainframe Dell E1505 T-mote x 2 Moteiv TMote Sky Motion Sensor Futurlec Directional Infrared Radial Sensor Smoke Sensor Mobile Phone Futurlec CO2 Sensor Nokia E61

  5. Demo Scenario

  6. Next Steps • Tmote Configurations • Tmote Sensor installation adjustment • Reconciling voltage difference between sensors and Tmote • Tmote TinyOS setup • Tmote Communication

  7. Software Architecture • Overview • Tmote: • Based on TinyOS, executes simple operations such as heartbeat and interrupt signals. • Main Frame: • When Tmote sends signal it acknowledges the notification and executes the text messaging program.

  8. S/W Diagram Alarm Heartbeat

  9. APIs • Tmote • Heartbeat() • Constantly sends the heartbeat signal to the mainframe on the periodic basis. • sensor_monitor(int fd) • Within the while loop keep polling the sensor to see if the fire sensor went off • fire_alarm() • Once sensor_monitor return the true value in the fire detection this function sends out the notification to the mainframe

  10. API continued • MainFrame • send_text(String crisis) • This function is in charge of the sending the request to the SMS text message service. • check_connection() • By pinging one of the most stable websites to see if the internet connection is fine. • sensor_checker(int fd) • Check if the sensor has detected anything. • heartbeat_monitor(int fd) • Make sure the smoke sensor still functions • More functions coming up!

  11. Lessons Learned • Tmote voltage Issue • Realized the need of reconciliation of the voltage difference between sensor and the tmote. -> Will resolve by implementing small circuit on breadboard • Alternative internet connection • Scan for other connections using built-in wireless device driver is not as easy as we thought. • Sunoco came up with taquitos and they are good too.
