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

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

Demo Scenario

Next Steps

• Tmote Configurations
• Tmote Sensor installation adjustment
• Reconciling voltage difference between sensors
  and Tmote
• Tmote TinyOS setup
• Tmote Communication

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.

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

12
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!

13
Lessons Learned

• Tmote voltage Issue
• Realized the need of reconciliation of the
  voltage difference between sensor and the tmote.
  -gt 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.
